Summary

CVE-2025-6335 is a low-severity Injection (CWE-74) vulnerability in Dedecms Dedecms. Its CVSS base score is 2.0 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A vulnerability identified as CVE-2025-6335 exists in DedeCMS versions up to 5.7.2 and is present in the Template Handler component within the file /include/dedetag.class.php. The issue stems from improper handling of the notes argument, which permits command injection and is tracked under CWE-74 and CWE-77. It received a CVSS 4.0 score of 2.0 reflecting high attack complexity requirements despite remote reachability.

An authenticated attacker with administrative privileges can supply crafted input to the affected parameter over the network, resulting in execution of arbitrary commands on the server. The exploit code has already been published, enabling potential reuse by threat actors who obtain the necessary credentials.

Public references consist of a GitHub disclosure and multiple Vuldb entries that document the flaw and proof-of-concept details, but no vendor advisory or patch information is provided in the available sources. The associated EPSS score has remained flat at 0.0102 with no observed increase since publication.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Secure engineering principles include proper neutralization and safe command construction practices.
