Detailsinfo

A vulnerability was found in SuiteCRM up to 7.15.0/8.9.2. It has been declared as critical. This vulnerability affects an unknown functionality of the file ModuleScanner.php. The manipulation of the argument checkFunction with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94.

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. A Critical Remote Code Execution (RCE) vulnerability exists in SuiteCRM 7.15.0 and 8.9.2, allowing authenticated administrators to execute arbitrary system commands. This vulnerability is a direct Patch Bypass of CVE-2024-49774. Although the vendor attempted to fix the issue in version 7.14.5, the underlying flaw in ModuleScanner.php regarding PHP token parsing remains. The scanner incorrectly resets its internal state ($checkFunction flag) when encountering any single-character token (such as =, ., or ;). This allows attackers to hide dangerous function calls (e.g., system(), exec()) using variable assignments or string concatenation, completely evading the MLP security controls. Versions 7.15.1 and 8.9.3 patch the issue.

The advisory is available at github.com. This vulnerability was named CVE-2026-29103 since 03/03/2026. The exploitation appears to be easy. The attack can be initiated remotely. Additional levels of successful authentication are necessary for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

By approaching the search of inurl:ModuleScanner.php it is possible to find vulnerable targets with Google Hacking.

Upgrading to version 7.15.1 or 8.9.3 eliminates this vulnerability. The upgrade is hosted for download at docs.suitecrm.com.
