Summary

CVE-2024-42850 is a critical-severity Weak Password Requirements (CWE-521) vulnerability in Silverpeas Silverpeas. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Account Manipulation (T1098); ranked in the top 2.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

CVE-2024-42850 affects the password change function in Silverpeas versions 6.4.2 and earlier. The flaw allows bypass of password complexity requirements and is classified under CWE-521, with a CVSS 3.1 base score of 9.8 reflecting network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.

An unauthenticated attacker can exploit the issue remotely to set passwords that violate the application's intended complexity rules. This weakens account protections and can lead to full system compromise when combined with other attack paths.

The listed references include the Silverpeas project site and a public GitHub repository containing vulnerability details, but no advisory text or patch information is supplied. The associated EPSS score is currently 0.4978 at its observed peak.
