CVE-2026-27490: CWE-331: Insufficient Entropy in Combodo iTop
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 has been addressed in version 3.2.3. The weakness could allow unauthorized access to these images due to the predictability of the secret.
AI Analysis
Technical Summary
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 is vulnerable to guessing or brute force attacks. This issue was fixed in version 3.2.3 by improving the randomness or protection mechanism for these secrets. The CVSS 3.1 score is 7.5, indicating a high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high confidentiality impact but no integrity or availability impact.
Potential Impact
An attacker can potentially access inline images that should be protected without authentication by exploiting the weak 24-bit pseudo-random secret. This leads to a confidentiality breach of the protected images. There is no impact on integrity or availability.
Mitigation Recommendations
Upgrade to Combodo iTop version 3.2.3 or later, where this vulnerability has been fixed. No other mitigation is indicated or necessary as the fix addresses the root cause.
