CVE-2020-25490

Status: ModifiedHigh (7.3)—

Lack of cryptographic signature verification in the Sqreen PHP agent daemon before 1.16.0 makes it easier for remote attackers to inject rules for execution inside the virtual machine.

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).
