AI Analysis
Technical Summary
CVE-2026-27462 describes a user enumeration vulnerability in Combodo iTop, a web-based IT service management tool. Before version 3.2.3, the application returns different responses during the password reset process depending on whether the username is valid or invalid. This discrepancy allows an attacker to determine valid usernames, which can facilitate further attacks. The vulnerability is classified under CWE-204 (Observable Response Discrepancy). The issue has been fixed in version 3.2.3.
Potential Impact
An attacker can enumerate valid usernames by analyzing the differences in responses during the password reset process. This can lead to targeted attacks against known user accounts. The CVSS v3.1 score is 7.5 (high severity), reflecting the network attack vector, low complexity, no privileges required, no user interaction, and high confidentiality impact. There is no impact on integrity or availability.
Mitigation Recommendations
Upgrade to Combodo iTop version 3.2.3 or later, where this user enumeration vulnerability has been fixed. No other specific mitigations are indicated.
