Vulnerabilities

An Improper link resolution before file access ('link following') vulnerability in the File Shredder module as used in Bitdefender Total Security and Internet Security on Windows allows a less-privileged local user to elevate rights by leveraging a race conditions via Symbolic Links. This issue affects Total Security: before 27.0.58.315; Internet Security: before 27.0.58.315.

The Bitdefender Napoca bare-metal hypervisor contains an out-of-bounds write vulnerability in the real-mode hook handler, implemented in napoca/kernel/handler.c. The handler uses a guest-controlled SS:SP-derived offset as an index into the 1MB RealModeMemory buffer without bounds validation. With SS=0xFFFF and ESP=0xFFFF, the computed offset can reach 0x10FFEF, exceeding the RealModeMemory buffer by 65,519 bytes. The IRET frame push can therefore write past the end of the buffer into the hypervisor heap. The product is end-of-life and unsupported when assigned.

A local privilege escalation vulnerability in Bitdefender Total Security versions prior to 27.0.47.241 allows low-privileged attackers to elevate privileges. The issue arises from bdservicehost.exe deleting files from a user-writable directory (C:\ProgramData\Atc\Feedback) without proper symbolic link validation, enabling arbitrary file deletion. This issue is chained with a file copy operation during network events and a filter driver bypass via DLL injection to achieve arbitrary file copy and code execution as elevated user.

An improper access restriction to a folder in Bitdefender Endpoint Security Tools for Mac (BEST) before 7.20.52.200087 allows local users with administrative privileges to bypass the configured uninstall password protection. An unauthorized user with sudo privileges can manually remove the application directory (/Applications/Endpoint Security for Mac.app/) and the related directories within /Library/Bitdefender/AVP without needing the uninstall password.

A Cross-Site Scripting (XSS) vulnerability has been identified in Psono-Client’s handling of vault entries of type website_password and bookmark, as used in Bitdefender SecurePass. The client does not properly sanitize the URL field in these entries. As a result, an attacker can craft a malicious vault entry (or trick a user into creating or importing one) with a javascript:URL. When the user interacts with this entry (for example, by clicking or opening it), the application will execute the malicious JavaScript in the context of the Psono vault. This allows an attacker to run arbitrary code in the victim’s browser, potentially giving them access to the user’s password vault and sensitive data.

A server-side request forgery (SSRF) vulnerability exists in the Bitdefender GravityZone Update Server when operating in Relay Mode. The HTTP proxy component on port 7074 uses a domain allowlist to restrict outbound requests, but fails to properly sanitize hostnames containing null-byte (%00) sequences. By crafting a request to a domain such as evil.com%00.bitdefender.com, an attacker can bypass the allowlist check, causing the proxy to forward requests to arbitrary external or internal systems.

A vulnerability in the sendMailFromRemoteSource method in Emails.php as used in Bitdefender GravityZone Console unsafely uses php unserialize() on user-supplied input without validation. By crafting a malicious serialized payload, an attacker can trigger PHP object injection, perform a file write, and gain arbitrary command execution on the host system.

A command injection vulnerability exists in the /check_image_and_trigger_recovery API endpoint of Bitdefender Box 1 (firmware version 1.3.11.490). This flaw allows an unauthenticated, network-adjacent attacker to execute arbitrary commands on the device, potentially leading to full remote code execution (RCE).

An untrusted search path vulnerability in testinitsigs.exe as used in Bitdefender Antivirus Free 2020 allows a low-privilege attacker to execute code as SYSTEM via a specially crafted DLL file.

A vulnerability in the BitdefenderVirusScanner binary as used in Bitdefender Virus Scanner for MacOS may allow .dynamic library injection (DYLD injection) without being blocked by AppleMobileFileIntegrity (AMFI). This issue is caused by the absence of Hardened Runtime or Library Validation signing. This issue affects Bitdefender Virus Scanner versions before 3.18.

A vulnerability has been identified in Bitdefender Total Security HTTPS scanning functionality where the software fails to properly validate website certificates. Specifically, if a site certificate lacks the "Server Authentication" specification in the Extended Key Usage extension, the product does not verify the certificate's compliance with the site, deeming such certificates as valid. This flaw could allow an attacker to perform a Man-in-the-Middle (MITM) attack, intercepting and potentially altering communications between the user and the website.

A verbose error handling issue in the proxy service implemented in the GravityZone Update Server allows an attacker to cause a server-side request forgery. This issue only affects GravityZone Console versions before 6.38.1-5 running only on premise.

A host whitelist parser issue in the proxy service implemented in the GravityZone Update Server allows an attacker to cause a server-side request forgery. This issue only affects GravityZone Console versions before 6.38.1-2 that are running only on premise.
