|
| Exploitation Conditions | The attacker must have high privileges (administrator access) to DedeCMS to access the template handler functionality. The attack is remote over the network. No user interaction is required. The vulnerability is in the /include/dedetag.class.php file, which processes the 'notes' argument. |
| Impact | CVSS 4.0 base score is 2.0 (Low) with vector AV:N/AC:L/AT:N/PR:H/UI:N, indicating high privileges required for remote exploitation. EPSS score is 0.17% (39th percentile), suggesting low exploitation probability. A public exploit exists but no CISA KEV listing, so exploitation is not confirmed active. The high privilege requirement significantly reduces real-world risk despite the critical classification in the description. |
| Exploit ScenarioDerived | An attacker with administrative privileges to DedeCMS can send a crafted request to the template handler with malicious commands in the 'notes' parameter, leading to remote code execution on the server. A public exploit is available, simplifying the attack. |

Alert meAnalysisAIv2 – Jul 26, 2026
Command injection in DedeCMS up to 5.7.2 allows remote authenticated attackers to execute arbitrary commands via the 'notes' parameter in /include/dedetag.class.php. A public exploit exists, but no active exploitation has been confirmed. EPSS score is low (0.17%), indicating limited exploitation likelihood.

RemediationAI
No official patch has been released by the vendor. As a workaround, restrict access to the /include/dedetag.class.php file via web server configuration (e.g., .htaccess deny) or disable the template handler feature if not required. Input validation on the 'notes' parameter should be implemented to block command injection characters. Monitor for updates from DedeCMS.
