Combodo iTop is a web-based IT service management tool. Prior to 3.2.3, iTop is vulnerable to PHP object injection in the user preference functionality, which can lead to remote code execution. This issue has been fixed in version 3.2.3.
AnalysisAI
PHP object injection in Combodo iTop's user preference functionality prior to version 3.2.3 enables authenticated remote attackers to achieve remote code execution on the underlying server. The vulnerability stems from deserializing attacker-controlled PHP objects without validation, with the CVSS Scope:Changed metric reflecting that successful exploitation escapes the application boundary to compromise the host. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid iTop user account with at minimum low-privilege access (PR:L per CVSS vector), meaning unauthenticated internet-facing attackers cannot directly exploit this vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.7 base score with vector AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N reflects a high-severity vulnerability with meaningful real-world risk, but several factors moderate the immediate threat level. … 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, which contains the vendor-confirmed fix per the GitHub Security Advisory GHSA-3mq5-p5vh-cw7r at https://github.com/Combodo/iTop/security/advisories/GHSA-3mq5-p5vh-cw7r. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Combodo iTop deployments and identify installations running versions prior to 3.2.3; restrict iTop administrative and preference management functions to essential personnel only and implement network-level access controls limiting iTop access to authorized internal networks. …
