Cisco PIX/ASA Firewall password modification
| cisco-pix-password-modification (28540) |  Medium Risk |
Description:

If two or more users make configuration changes concurrently or the software crashes, multiple passwords stored in the startup configuration could be changed without user interaction. This would result in administrator's being locked out of the device or possible unauthorized access to the device if an attacker could guess the new password.
