CVE-2020-23355

Status: ModifiedHigh (7.5)—

** PRODUCT NOT SUPPORTED WHEN ASSIGNED ** Codiad 2.8.4 /componetns/user/class.user.php:Authenticate() is vulnerable in magic hash authentication bypass. If encrypted or hash value for the passwords form certain formats of magic hash, e.g, 0e123, another hash value 0e234 something can successfully authenticate.

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).
