CVE-2022-24881

Status: ModifiedCritical (9.8)—

Ballcat Codegen provides the function of online editing code to generate templates. In versions prior to 1.0.0.beta.2, attackers can implement remote code execution through malicious code injection of the template engine. This happens because Velocity and freemarker templates are introduced but input verification is not done. The fault is rectified in version 1.0.0.beta.2.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
