AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

MantisBT before 1.2.3 has a stored XSS vulnerability in the Summary field on the summary page.

Vulnerability

Cross-site scripting (XSS) vulnerability in core/summary_api.php in MantisBT before version 1.2.3 allows remote attackers to inject arbitrary web script or HTML via the Summary field (bug summary). The issue is fixed by using string_display_line() instead of string_html_specialchars() or direct output [1][2][3][4]. Affected versions include all prior to 1.2.3.

Exploitation

An attacker can exploit this by entering malicious JavaScript or HTML into a bug's Summary field, which is then displayed on the summary page without proper sanitization. No prior authentication is required if the attacker can create or modify bugs, though in typical configurations only authenticated users with report or update permissions can set the Summary field. The attacker does not need direct network access to the summary page beyond normal HTTP requests [4].

Impact

Successful exploitation leads to arbitrary script execution in the context of the victim's browser when they view the summary page. This can result in session hijacking, information disclosure, or other client-side attacks. The compromise occurs at the user's privilege level.

Mitigation

MantisBT version 1.2.3, released on September 2, 2010, includes the fix. Administrators should upgrade to at least 1.2.3 or later. The official patch replaces string_html_specialchars() and direct output with string_display_line() in core/summary_api.php [4]. No workarounds other than upgrading are documented. The issue is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog.
