Summary

OpenCATS before 0.12.0 contains a stored cross-site scripting vulnerability allowing a low-privileged authenticated user to inject HTML/JavaScript payloads via Candidate, Company, Contact, Job Order, or List name/title fields. The value is stored unsanitized and later rendered unescaped in the 'Recent' (MRU) navigation panel shown on nearly every page via getFormatted() in lib/MRU.php. An attacker can execute arbitrary JavaScript in the session of any other user, including Site Administrators, enabling session/cookie theft and escalation to full administrative control.

Risk Assessment

A low-privileged user can hijack an administrator's session and gain full control of the application. This can lead to data theft and further attacks within the organization.

Recommendation

Upgrade OpenCATS to version 0.12.0 or later. Additionally, consider deploying a Content-Security-Policy header and escaping output in the MRU panel.

Original NVD description (English source)

OpenCATS before 0.12.0 contains a stored cross-site scripting vulnerability that allows a low-privileged authenticated user to inject HTML/JavaScript payloads by setting a Candidate, Company, Contact, Job Order, or List name/title field, which is stored unsanitized and later rendered unescaped in the 'Recent' (MRU) navigation panel displayed on nearly every page via lib/MRU.php's getFormatted() function. Attackers can exploit this by crafting a malicious record name that executes arbitrary JavaScript in the session of any other user, including Site Administrators, who views the record, enabling session/cookie theft and privilege escalation to full administrative control.
