CVE-2025-67031: n/a
ORSEE (Online Recruitment System for Economic Experiments) 3.1.0 contains an authenticated Remote Code Execution vulnerability in the participant profile field processing subsystem. Certain field configurations accept values beginning with the prefix "func:" which are passed directly into an eval() call inside tagsets/participant.php and tagsets/options.php.
AI Analysis
Technical Summary
CVE-2025-67031 affects ORSEE version 3.1.0 and arises from improper handling of participant profile fields that accept input starting with "func:". These inputs are passed directly into an eval() call in the files tagsets/participant.php and tagsets/options.php, enabling authenticated users to execute arbitrary code remotely. The vulnerability is classified under CWE-94 (Improper Control of Generation of Code). The CVSS 3.1 base score is 6.3 with vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L, reflecting network attack vector, low attack complexity, required privileges, no user interaction, unchanged scope, and low impact on confidentiality, integrity, and availability.
Potential Impact
An authenticated user with limited privileges can exploit this vulnerability to execute arbitrary code on the server hosting ORSEE 3.1.0. This could lead to partial compromise of the system, including potential unauthorized actions or data manipulation. The impact is rated medium based on the CVSS score and the requirement for authentication.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to trusted users only and consider additional monitoring or compensating controls to limit exposure. Avoid using vulnerable versions in production environments if possible.
