CVE-2009-1203

Status: ModifiedMedium (6)—💥 Exploit

WebVPN on the Cisco Adaptive Security Appliances (ASA) device with software 8.0(4), 8.1.2, and 8.2.1 does not properly distinguish its own login screen from the login screens it produces for third-party (1) FTP and (2) CIFS servers, which makes it easier for remote attackers to trick a user into sending WebVPN credentials to an arbitrary server via a URL associated with that server, aka Bug ID CSCsy80709.

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
