CVE-2026-27490: CWE-331: Insufficient Entropy in Combodo iTop
Description
Combodo iTop versions prior to 3.2.3 use a weak 24-bit pseudo-random secret to protect inline images accessible without authentication. This insufficient entropy vulnerability allows potential attackers to predict or guess the secret, potentially exposing these images. The issue has been fixed in version 3.2.3.

Technical Analysis
CVE-2026-27490 describes an insufficient entropy vulnerability (CWE-331) in Combodo iTop, a web-based IT service management tool. Versions before 3.2.3 protect unauthenticated inline images with a weak 24-bit pseudo-random secret, which does not provide adequate randomness. This weakness could allow unauthorized access to protected inline images. The vulnerability has been addressed and fixed in version 3.2.3.
Potential Impact
The vulnerability allows unauthorized users to potentially access inline images that should be protected, due to the weak 24-bit pseudo-random secret. The CVSS score of 7.5 (high) reflects the network attack vector, low attack complexity, no privileges or user interaction required, and high confidentiality impact. There is no impact on integrity or availability. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade to Combodo iTop version 3.2.3 or later, where this vulnerability has been fixed by improving the entropy of the secret protecting inline images. No other mitigation is indicated by the vendor advisory.
