| CVE-2017-3623 +1 in the same advisory: …3622 | Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: Kernel RPC). For supported versions that are affected see note. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Solaris. While the vulnerability is in Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Solaris. Note: CVE-2017-3623 is assigned for "Ebbisland". Solaris 10 systems which have had any Kernel patch installed after, or updated via patching tools since 2012-01-26 are not impacted. Also, any Solaris 10 system installed with Solaris 10 1/13 (Solaris 10 Update 11) are not vulnerable. Solaris 11 is not impacted by this issue. CVSS 3.0 Base Score 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

| CVE-2017-5638 | Unauthenticated RCE in Apache Struts Jakarta Multipart parser CVE-2017-5638 is an improper input validation flaw (CWE-20) in the Jakarta Multipart parser of Apache Struts, in which the parser mishandles the Content-Type value of a file upload and allows malicious upload leading to remote code execution. It is triggered remotely without authentication by sending a crafted Content-Type header in a multipart request to a Struts endpoint; no valid upload or credentials are required. A successful attacker gains code execution in the security context of the application server, which typically enables host compromise, data theft, or ransomware deployment. Any organization running Apache Struts applications that use the Jakarta Multipart parser is affected; the provided data specifies only "Apache Struts" and gives no version ranges. Exploitation is confirmed in the wild: the flaw is listed in CISA KEV (added 2021-11-03) with known ransomware use, EPSS assigns it roughly a 100% exploitation probability (100th percentile), and no public PoC is catalogued in the source data. Do: Apply updates per vendor instructions: upgrade Apache Struts to the releases that fix this flaw (2.3.32 / 2.5.10.1 or later, per Apache advisory S2-045), and check for Struts jars bundled inside application packages and vendor appliances. Prioritize internet-facing apps, and as an interim mitigation validate or filter the Content-Type header on multipart requests. Because exploitation is in the wild and ransomware use is known, also review web and application server logs for evidence of successful compromise. | 9.8 | 100% | KEV ransomware PoC ×10 |

Oracle has pushed out a record-breaking 299 fixes for vulnerabilities in its many, many products, and among them is a Solaris 10 bug whose existence has been revealed through Shadow Brokers’ latest data dump.
The Oracle Critical Patch Update for April 2017, detailed in this advisory, addresses vulnerabilities in Oracle Database Server, Fusion Middleware, PeopleSoft Enterprise, Financial Services Applications, MySQL Product Suite, Java, and many other offerings.
“The patch update contains 40 vulnerabilities assessed critical (CVSS base score 9.0-10.0), including 25 rated 10.0,” ERPScan researchers have noted.
Among these is CVE-2017-3623, the Solaris kernel RPC vulnerability that is targeted in the EBBISLAND (aka EBBSHAVE) exploit purportedly created by the NSA, and which has been leaked last Friday.
As explained by Oracle: “Solaris 10 systems which have had any Kernel patch installed after, or updated via patching tools since 2012-01-26 are not impacted. Also, any Solaris 10 system installed with Solaris 10 1/13 (Solaris 10 Update 11) are not vulnerable. Solaris 11 is not impacted by this issue.” Older, unsupported versions of the OS won’t be receiving a patch.
Solaris 11 is also not vulnerable to NSA’s EXTREMEPARR tool, also leaked on Friday, which takes advantage of a local privilege escalation hole in the Common Desktop Environment on Solaris (CVE-2017-3622).
CVE-2017-5638, a critical vulnerability in the Apache Struts framework, which is included in many of Oracle’s products, has also been plugged.
But if you thing that the vulnerabilities with a less high rating do not present a significant risk to security, you’re wrong.
“For example, a remotely exploitable vulnerability in Oracle E-Business Suite rated 9.1 (the main business applications from the vendor) allows an attacker to read all key business data from the database without authorization,” ERPScan researchers pointed out.
Finally, the Java updates plug eight vulnerabilities, seven of which may be remotely exploitable without authentication. All of them are affect client deployments of Java (i.e. individual end-users who still have it installed).
The next Oracle Critical Patch Update is scheduled for July 18, 2017.
