Summary

CVE-2024-26331 is a high-severity Improper Authentication (CWE-287) vulnerability in Sensepost (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, ranked in the top 1.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

ReCrystallize Server version 5.10.0.0 contains an improper authentication vulnerability tracked as CVE-2024-26331 and CWE-287. The product relies on an authorization mechanism driven solely by a cookie value that is not bound to any session identifier, allowing the cookie to be altered directly by an attacker.

An unauthenticated remote attacker can modify the cookie contents either inside a browser or through separate client-side code to supply an expected value and thereby bypass authentication entirely. Successful exploitation grants access to restricted resources, consistent with the CVSS 3.1 score of 7.5 that reflects high confidentiality impact over a network with low attack complexity.

The two referenced sources consist of a SensePost disclosure write-up and the vendor product page; neither supplies mitigation steps or patch details in the available information. The associated EPSS score has remained at a peak of 0.6786 with no indicated rise from a lower baseline.
