DescriptionCVE.org

A security flaw has been discovered in DedeCMS 5.7.118. Impacted is an unknown function of the file /plus/search.php of the component Column Management. Performing a manipulation of the argument Column Name results in code injection. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks.

AnalysisAI

Code injection in DedeCMS 5.7.118 exposes high-privileged remote attackers to arbitrary PHP code execution via the Column Name parameter in the Column Management component of /plus/search.php. The exploit document on GitHub describes a cache file writing mechanism through which attacker-supplied input is persisted to disk and subsequently executed by the PHP runtime. …

Vulnerability AssessmentAI

Exploitation Exploitation strictly requires an authenticated session with high-privilege (administrator-level) access to the DedeCMS backend, as confirmed by the CVSS PR:H metric. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.1 (AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L) places this at medium severity, but the impact ratings warrant scrutiny: the vulnerability is tagged RCE and references a cache file write primitive, yet the vendor-assigned impact is Low across all three pillars. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained valid DedeCMS administrator credentials - through credential stuffing, phishing, or reuse from a prior breach - logs into the backend and navigates to the Column Management interface. They supply a PHP payload as the Column Name value, which the application writes into a cache file on disk. …
Remediation No vendor-released patch has been identified at time of analysis; monitor VulDB (https://vuldb.com/vuln/377878) and DedeCMS official channels for a fix. … Detailed patch versions, workarounds, and compensating controls in full report.
