Title: Icon Labs Iconfidant SSH Multiple Denial of Service Vulnerabilities
Severity: MODERATE
Description:
Icon Labs Iconfidant SSH server is prone to three vulnerabilities that can cause denial-of-service conditions.
The issues are triggered when:
- multiple authentication attempts are performed over a short period of time.
- an authentication attempt occurs simultaneously with certain management operations.
- certain invalid authentication credentials are provided during authentication.
Attackers can leverage these issue to cause instability that may crash affected servers. Successful exploits will deny service for legitimate users.
Versions prior to Iconfidant SSH 2.3.8 are vulnerable.
Affected Products:
- Icon Labs Iconfidant SSH 2.3.7
