Combodo iTop is a web based IT service management tool. Prior to 3.2.3, there is a Reflected Cross-Site Scripting (XSS) vulnerability in the universal search. This issue has been fixed in version 3.2.3.
AnalysisAI
Reflected XSS in Combodo iTop's universal search feature (all versions prior to 3.2.3) allows an authenticated attacker to inject arbitrary JavaScript via the OQL filter parameter, which executes in a victim's browser upon visiting a crafted URL. The root cause is direct HTML output of the user-supplied OQL query string in UniversalSearch.php without sanitization, confirmed by the patch commit adding utils::EscapeHtml(). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker possesses at least a low-privilege authenticated iTop account (CVSS PR:L confirms authentication is required - this is not unauthenticated). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.0 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H) captures a network-accessible, low-complexity flaw but with two meaningful friction points: the attacker must hold valid low-privilege credentials (PR:L), and a victim must follow a crafted URL while authenticated (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Combodo iTop to version 3.2.3 or later; this is the vendor-released patch that resolves the vulnerability by applying utils::EscapeHtml() to the OQL filter output in UniversalSearch.php (see commit 7bfa14a8744cc599caf0ed347022f8267793d6d9 and advisory GHSA-6qgh-xqjr-4pv7 at https://github.com/Combodo/iTop/security/advisories/GHSA-6qgh-xqjr-4pv7). … Detailed patch versions, workarounds, and compensating controls in full report. |
