CVE-2011-10013 in Issue Tracking System
Summary
by MITRE • 08/14/2025
Traq versions 2.0 through 2.3 contain a remote code execution vulnerability in the admincp/common.php script. The flawed authorization logic fails to halt execution after a failed access check, allowing unauthenticated users to reach admin-only functionality. This can be exploited via plugins.php to inject and execute arbitrary PHP code.

The vulnerability identified as CVE-2011-10013 affects Traq versions 2.0 through 2.3 and represents a critical remote code execution flaw that stems from inadequate authentication and authorization controls. This vulnerability resides within the admincp/common.php script where the application fails to properly validate user permissions before allowing access to administrative functions. The flaw demonstrates a classic broken access control pattern that violates fundamental security principles and creates a pathway for malicious actors to bypass authentication mechanisms entirely.
The technical implementation of this vulnerability exploits a specific authorization logic flaw that allows unauthenticated users to traverse the application's access control checks. When users attempt to access the admin panel through the plugins.php endpoint, the system does not properly terminate execution upon detecting unauthorized access attempts. This failure creates an execution path where malicious input can be processed without proper authentication verification, effectively granting administrative privileges to any remote attacker. The vulnerability specifically targets the admincp/common.php file which serves as a central access point for administrative functionality, making it a prime target for exploitation.
The operational impact of this vulnerability is severe and encompasses full system compromise capabilities for attackers who can leverage this flaw. Once exploited, the vulnerability allows remote code execution with administrative privileges, enabling attackers to modify application configuration, inject malicious code, access sensitive data, and potentially establish persistent backdoors. The attack vector through plugins.php represents a particularly dangerous pathway since plugins often require elevated privileges and may have direct access to system resources. This vulnerability essentially transforms any unauthenticated user into a privileged administrator, creating a significant risk for data breaches, service disruption, and unauthorized system modifications.
Security professionals should implement immediate mitigations including applying the latest available patches from Traq developers, implementing network segmentation to restrict access to administrative endpoints, and deploying web application firewalls to monitor and block suspicious requests targeting the vulnerable admincp/common.php script. The vulnerability aligns with CWE-285 which addresses improper authorization issues, and maps to ATT&CK technique T1078 for valid accounts and T1566 for spearphishing with a specific focus on credential access and privilege escalation. Organizations should also conduct comprehensive security assessments to identify similar authorization flaws in other application components and implement proper input validation and access control measures to prevent similar vulnerabilities from occurring in the future.
