Synopsis

Description

 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3949-1 [email protected] https://www.debian.org/lts/security/ Abhijith PA November 11, 2024 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : ruby-saml Version : 1.11.0-1+deb11u1 CVE ID : CVE-2024-45409


 It was discovered that ruby-saml, a library for implementing the client side of a SAML authorization does not properly verify the signature of the SAML Response. An unauthenticated attacker with access to any signed saml document (by the IdP) can thus forge a SAML Response/Assertion with arbitrary contents. This would allow the attacker to log in as arbitrary user within the vulnerable system.

 For Debian 11 bullseye, this problem has been fixed in version 1.11.0-1+deb11u1.

 We recommend that you upgrade your ruby-saml packages.

 For the detailed security status of ruby-saml please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/ruby-saml

 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ruby-saml packages.
