Vulnerabilities

A broken access control may allow an authenticated user to perform a horizontal privilege escalation. The vulnerability only impacts specific configurations.

deepHas provides a test for the existence of a nested object key and optionally returns that key. A prototype pollution vulnerability exists in version 1.0.7 of the deephas npm package that allows an attacker to modify global object behavior. This issue was fixed in version 1.0.8.

Missing Authentication for Critical Function vulnerability in Sharp Display Solutions Media Player MP-01 All Verisons allows a attacker may access to the web interface of the affected product without authentication and change settings or perform other operations, and deliver content from the authoring software to the affected product without authentication.

Improper Validation of Integrity Check Value vulnerability in Sharp Display Solutions projectors allows a attacker may create and run unauthorized firmware.

Sharp and Toshiba Tec MFPs improperly process HTTP authentication requests, resulting in an authentication bypass vulnerability.

RestSharp is a Simple REST and HTTP API Client for .NET. The second argument to `RestRequest.AddHeader` (the header value) is vulnerable to CRLF injection. The same applies to `RestRequest.AddOrUpdateHeader` and `RestClient.AddDefaultHeader`. The way HTTP headers are added to a request is via the `HttpHeaders.TryAddWithoutValidation` method which does not check for CRLF characters in the header value. This means that any headers from a `RestSharp.RequestHeaders` object are added to the request in such a way that they are vulnerable to CRLF-injection. In general, CRLF-injection into a HTTP header (when using HTTP/1.1) means that one can inject additional HTTP headers or smuggle whole HTTP requests. If an application using the RestSharp library passes a user-controllable value through to a header, then that application becomes vulnerable to CRLF-injection. This is not necessarily a security issue for a command line application like the one above, but if such code were present in a web application then it becomes vulnerable to request splitting (as shown in the PoC) and thus Server Side Request Forgery. Strictly speaking this is a potential vulnerability in applications using RestSharp, not in RestSharp itself, but I would argue that at the very least there needs to be a warning about this behaviour in the RestSharp documentation. RestSharp has addressed this issue in version 112.0.0. All users are advised to upgrade. There are no known workarounds for this vulnerability.

The Remote Content Shortcode plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.5 via the remote_content shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

Cross-site scripting vulnerability in Energy Management Controller with Cloud Services JH-RVB1 /JH-RV11 Ver.B0.1.9.1 and earlier allows a network-adjacent unauthenticated attacker to execute an arbitrary script on the web browser of the user who is accessing the management page of the affected product.

SmartStar Software CWS is a web-based integration platform, its file uploading function does not restrict upload of file with dangerous type. An unauthenticated remote attacker can exploit this vulnerability to upload arbitrary files to perform arbitrary command or disrupt service.

Command injection vulnerability in nw_interface.html in SHARP multifunction printers (MFPs)'s Digital Full-color Multifunctional System 202 or earlier, 120 or earlier, 600 or earlier, 121 or earlier, 500 or earlier, 402 or earlier, 790 or earlier, and Digital Multifunctional System (Monochrome) 200 or earlier, 211 or earlier, 102 or earlier, 453 or earlier, 400 or earlier, 202 or earlier, 602 or earlier, 500 or earlier, 401 or earlier allows remote attackers to execute arbitrary commands via unspecified vectors.

UniSharp laravel-filemanager (aka Laravel Filemanager) before 2.6.4 allows download?working_dir=%2F.. directory traversal to read arbitrary files, as exploited in the wild in June 2022. This is related to league/flysystem before 2.0.0.

sharp is an application for Node.js image processing. Prior to version 0.30.5, there is a possible vulnerability in logic that is run only at `npm install` time when installing versions of `sharp` prior to the latest v0.30.5. If an attacker has the ability to set the value of the `PKG_CONFIG_PATH` environment variable in a build environment then they might be able to use this to inject an arbitrary command at `npm install` time. This is not part of any runtime code, does not affect Windows users at all, and is unlikely to affect anyone that already cares about the security of their build environment. This problem is fixed in version 0.30.5.

SharpZipLib (or #ziplib) is a Zip, GZip, Tar and BZip2 library. Prior to version 1.3.3, a TAR file entry `../evil.txt` may be extracted in the parent directory of `destFolder`. This leads to arbitrary file write that may lead to code execution. The vulnerability was patched in version 1.3.3.

This affects versions of the package unisharp/laravel-filemanager before 2.6.2. The upload() function does not sufficiently validate the file type when uploading. An attacker may be able to reproduce the following steps: 1. Install a package with a web Laravel application. 2. Navigate to the Upload window 3. Upload an image file, then capture the request 4. Edit the request contents with a malicious file (webshell) 5. Enter the path of file uploaded on URL - Remote Code Execution **Note:** Prevention for bad extensions can be done by using a whitelist in the config file(lfm.php). Corresponding document can be found in [here](https://unisharp.github.io/laravel-filemanager/configfolder-categories).

SharpCompress is a fully managed C# library to deal with many compression types and formats. Versions prior to 0.29.0 are vulnerable to partial path traversal. SharpCompress recreates a hierarchy of directories under destinationDirectory if ExtractFullPath is set to true in options. In order to prevent extraction outside the destination directory the destinationFileName path is verified to begin with fullDestinationDirectoryPath. However, prior to version 0.29.0, it is not enforced that fullDestinationDirectoryPath ends with slash. If the destinationDirectory is not slash terminated like `/home/user/dir` it is possible to create a file with a name thats begins as the destination directory one level up from the directory, i.e. `/home/user/dir.sh`. Because of the file name and destination directory constraints the arbitrary file creation impact is limited and depends on the use case. This issue is fixed in SharpCompress version 0.29.0.

RestSharp < 106.11.8-alpha.0.13 uses a regular expression which is vulnerable to Regular Expression Denial of Service (ReDoS) when converting strings into DateTimes. If a server responds with a malicious string, the client using RestSharp will be stuck processing it for an exceedingly long time. Thus the remote server can trigger Denial of Service.

Prototype pollution vulnerability in 'deephas' versions 1.0.0 through 1.0.5 allows attacker to cause a denial of service and may lead to remote code execution.

CVE-2020-16009 is a type confusion vulnerability (CWE-843) in the V8 JavaScript engine used by Google Chromium, which can lead to heap corruption (CWE-787). A remote attacker triggers it by getting a user to load a specially crafted HTML page, such as via a malicious or compromised website. Successful exploitation corrupts the heap and can potentially allow the attacker to execute code in the context of the affected browser. Any Chromium-based browser or application embedding V8 is affected, including Google Chrome, Microsoft Edge, and Opera, meaning the affected population is effectively the entire Chromium user base worldwide. CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2021-11-03, confirming exploitation in the wild, with an EPSS probability of 48.3% (99th percentile); ransomware use is unknown and no public PoC is known.

Do: Apply the vendor update per CISA's required action: update all Chromium-based browsers (Chrome, Edge, Opera, and derivatives) to the latest stable releases from each vendor and restart browsers afterward. Inventory any embedded or packaged Chromium/V8 runtimes in other applications and update them as their maintainers ship fixes. Given confirmed in-the-wild exploitation and high EPSS, prioritize patching endpoints used for web browsing by high-risk users first.

SHARP AQUOS series (AQUOS SH-M02 build number 01.00.05 and earlier, AQUOS SH-RM02 build number 01.00.04 and earlier, AQUOS mini SH-M03 build number 01.00.04 and earlier, AQUOS Keitai SH-N01 build number 01.00.01 and earlier, AQUOS L2 (UQ mobile/J:COM) build number 01.00.05 and earlier, AQUOS sense lite SH-M05 build number 03.00.04 and earlier, AQUOS sense (UQ mobile) build number 03.00.03 and earlier, AQUOS compact SH-M06 build number 02.00.02 and earlier, AQUOS sense plus SH-M07 build number 02.00.02 and earlier, AQUOS sense2 SH-M08 build number 02.00.05 and earlier, and AQUOS sense2 (UQ mobile) build number 02.00.06 and earlier) allow an attacker to obtain the sensitive information of the device via malicious applications installed on the device.

Xiaomi Mi 5s Plus devices allow attackers to trigger touchscreen anomalies via a radio signal between 198 kHz and 203 kHz, as demonstrated by a transmitter and antenna hidden just beneath the surface of a coffee-shop table, aka Ghost Touch.

The Crestron AM-100 firmware 1.6.0.2, Crestron AM-101 firmware 2.7.0.1, Barco wePresent WiPG-1000P firmware 2.3.0.10, Barco wePresent WiPG-1600W before firmware 2.4.1.19, Extron ShareLink 200/250 firmware 2.0.3.4, Teq AV IT WIPS710 firmware 1.1.0.7, SHARP PN-L703WA firmware 1.4.2.3, Optoma WPS-Pro firmware 1.0.0.5, Blackbox HD WPS firmware 1.0.0.5, InFocus LiteShow3 firmware 1.0.16, and InFocus LiteShow4 2.0.0.7 are vulnerable to a stack buffer overflow in libAwgCgi.so's PARSERtoCHAR function. A remote, unauthenticated attacker can use this vulnerability to execute arbitrary code as root via a crafted request to the return.cgi endpoint.

CVE-2019-3929 is an unauthenticated OS command injection in the file_transfer.cgi HTTP endpoint of the embedded web server used by a family of wireless presentation gateways. A remote attacker who can reach the device's web interface sends a crafted request to file_transfer.cgi, causing arbitrary operating system commands to run as root. Successful exploitation yields full compromise of the device, which typically sits inside the corporate network and can be used as a pivot into internal systems. Affected products span Crestron (AM-100, AM-101), Barco wePresent (WiPG-1000P, WiPG-1600W), Extron ShareLink 200/250, Teq AV IT WIPS710, SHARP PN-L703WA, Optoma WPS-Pro, Blackbox HD WPS, and InFocus LiteShow3/LiteShow4 — most of which are OEM variants of the same platform. The flaw has a public proof of concept (Exploit-DB 46786, Tenable TRA-2019-20), a 99% EPSS score, and is listed in CISA's Known Exploited Vulnerabilities catalog as of 2022-04-15, indicating exploitation in the wild.

Do: Apply vendor firmware updates per CISA's required action — for Barco wePresent WiPG-1600W this means 2.4.1.19 or later, and owners of the other listed models should obtain the fixed firmware from each vendor's advisory (Tenable TRA-2019-20 / Exploit-DB 46786). Until patched, restrict the devices' web interface (including the file_transfer.cgi endpoint) from internet exposure and limit access to trusted management or presentation VLANs. Check device logs and network traffic for unexpected requests to file_transfer.cgi, and treat any internet-facing unit as potentially compromised since the flaw allows unauthenticated root-level access.

SharpZipLib before 1.0 RC1 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in a Zip archive entry that is mishandled during extraction. This vulnerability is also known as 'Zip-Slip'.
