Ivanti Connect Secure Unauthenticated Remote Code Execution
This Metasploit module chains a server side request forgery (SSRF) vulnerability (CVE-2024-21893) and a command injection vulnerability (CVE-2024-21887) to exploit vulnerable instances of either Ivanti Connect Secure or Ivanti Policy Secure, to achieve unauthenticated remote code execution. All currently supported versions 9.x and 22.x are vulnerable, prior to the vendor patch released on Feb 1, 2024. It is unknown if unsupported versions 8.x and below are also vulnerable.

A pair of zero-day flaws identified in Ivanti Connect Secure (ICS) and Policy Secure have been chained by suspected China-linked nation-state actors to breach less than 10 customers. Cybersecurity firm Volexity, which identified the activity on the network of one of its customers in the second week of December 2023, attributed it to a hacking group it tracks under the name UTA0178

Ubuntu Security Notice 6274-1 - Jurien de Jong discovered that XMLTooling did not properly handle certain KeyInfo element content within an XML signature. An attacker could possibly use this issue to achieve server-side request forgery.
Shibboleth XMLTooling before 3.2.4, as used in OpenSAML and Shibboleth Service Provider, allows SSRF via a crafted KeyInfo element. (This is fixed in, for example, Shibboleth Service Provider 3.4.1.3 on Windows.)
