CVE-2026-46512: CWE-94: Improper Control of Generation of Code ('Code Injection') in mwtcmi frogman
Frogman provides headless PBX control through MCP and HTTP API. Prior to 1.6.2, fm_dialplan_apply accepted template parameters including greeting, dest, url, extension, code, and file, and Tools/DialplanApply.php wrote Dialplan/Templates.php output to extensions_custom.conf while only Dialplan/TemplateBase.php:38-42 sanitized contextName(), allowing a PERM_WRITE caller using confirm:true to inject arbitrary Asterisk directives such as System(), Set(SHELL(...)), Goto, or Macro. This issue is fixed in version 1.6.2.
AI Analysis
Technical Summary
The vulnerability in mwtcmi frogman versions before 1.6.2 involves improper control of code generation (CWE-94) in the fm_dialplan_apply function. This function accepted several template parameters and wrote output to extensions_custom.conf with insufficient sanitization, enabling a user with PERM_WRITE privileges and confirm:true to inject arbitrary Asterisk dialplan directives. This could lead to remote code execution or other severe impacts on the PBX system. The vulnerability is fixed in version 1.6.2.
Potential Impact
An attacker with PERM_WRITE privileges and the ability to use confirm:true can inject arbitrary Asterisk directives, potentially leading to full system compromise, including remote code execution and disruption of PBX services. The CVSS score of 9.9 reflects the critical nature of this vulnerability with high confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Upgrade to mwtcmi frogman version 1.6.2 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Until upgrading, restrict PERM_WRITE access and avoid using confirm:true with untrusted inputs.
