CVE-2026-45562 Sep 28, 17:36 HIGH PATCH This Week

Command injection in the FreePBX Music on Hold (MoH) module lets anyone holding an existing FreePBX administrator account run arbitrary system commands with the privileges of the Asterisk service, because a POST parameter that defines a custom Asterisk application is stored in the database unsanitized and later written verbatim into musiconhold_additional.conf, which Asterisk loads and executes. Deployments running FreePBX prior to 16.0.4 or 17.0.6 with the MoH module enabled and a functioning Asterisk backend are exposed; the vendor has patched the issue in 16.0.4 and 17.0.6. The required admin credentials (PR:L in the published CVSS 4.0 vector, PR:H in the independent CVSS 3.1 assessment) make this a post-authentication privilege-to-code-execution flaw rather than a pre-auth remote takeover, so realistic risk is confined to insider misuse, credential theft, or chaining from another auth bypass; no public exploit code and no confirmed active exploitation (CISA KEV) are identified in the available intelligence.

Command injection in the FreePBX Music on Hold (MoH) module lets anyone holding an existing FreePBX administrator account run arbitrary system commands with the privileges of the Asterisk service, because a POST parameter that defines a custom Asterisk application is stored in the database unsanitized and later written verbatim into musiconhold_additional.conf, which Asterisk loads and executes. Deployments running FreePBX prior to 16.0.4 or 17.0.6 with the MoH module enabled and a functioning Asterisk backend are exposed; the vendor has patched the issue in 16.0.4 and 17.0.6. The required admin credentials (PR:L in the published CVSS 4.0 vector, PR:H in the independent CVSS 3.1 assessment) make this a post-authentication privilege-to-code-execution flaw rather than a pre-auth remote takeover, so realistic risk is confined to insider misuse, credential theft, or chaining from another auth bypass; no public exploit code and no confirmed active exploitation (CISA KEV) are identified in the available intelligence.
