## Technical details

A code injection vulnerability exists in DedeCMS 5.7.118 within the Column Management component, specifically involving the /plus/search.php file. The root cause is improper neutralization of special elements in the 'Column Name' argument, which is subsequently written to a cache file. An authenticated attacker with high privileges (PR:H) can exploit this via a network request to achieve remote code execution (RCE). While the CVSS score is moderate due to the requirement for high privileges, a public exploit has been released, increasing the risk of exploitation in environments where administrative accounts are compromised.
