The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Request Tracker is vulnerable to a reflected cross-site scripting (XSS) vulnerability via the Page     parameter in GET requests. An attacker can craft a URL that, when opened, results in arbitrary JavaScript     execution in the victim's browser. This vulnerability affects versions from 5.0.4 up to 5.0.9 and from     6.0.0 up to 6.0.2. (CVE-2026-6841)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6324 advisory.

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8506-1 advisory.

    Aleksander Iwicki discovered that Request Tracker did not properly sanitize the search Page URL     parameter. A remote attacker could possibly use this issue to conduct a reflected cross-site scripting     attack. (CVE-2026-6841)

    It was discovered that Request Tracker did not properly sanitize user- controlled data written to     spreadsheet exports of search results. A remote attacker could possibly use this issue to conduct a     spreadsheet (CSV/formula) injection attack, causing spreadsheet applications to interpret crafted values     as formulas or macros when the file is opened. (CVE-2026-41073)

    It was discovered that Request Tracker did not properly validate input incorporated into database queries     via the entry_aggregator parameter in JSON search. An authenticated user could possibly use this issue to     perform SQL injection attacks and read or modify data in the RT database. (CVE-2026-41075)

    It was discovered that Request Tracker contained an authentication bypass when configured to authenticate     users against an LDAP or Active Directory server. Under certain LDAP server configurations, a remote     attacker could possibly use this issue to authenticate as any LDAP-backed RT user without supplying valid     credentials. (CVE-2026-41076)

    It was discovered that Request Tracker served certain uploaded content inline rather than as an     attachment. A remote attacker could possibly use this issue to conduct a cross-site scripting attack.
    (CVE-2026-44229)

    It was discovered that Request Tracker did not properly sanitize input on search-results chart pages. A     remote attacker could possibly use this issue to conduct a reflected cross-site scripting attack.
    (CVE-2026-44230)

    Jeroen Gui discovered that Request Tracker did not properly restrict access to the REST 2.0 user     collection endpoint. A privileged user could possibly use this issue to obtain authentication credentials     belonging to other users, including administrators, resulting in privilege escalation and information     disclosure. (CVE-2026-44231)
