Title: Juniper NetScreen-Security Manager Remote Denial of Service Vulnerability
Severity: MODERATE
Description:
Juniper NetScreen-Security Manager (NSM) is used to centrally manage a Juniper Networks NetScreen security environment.
Juniper NSM is prone to a remote denial of service vulnerability. This issue arises because the application fails to handle exceptional conditions in a proper manner.
The vulnerability presents itself when the guiSrv process running on TCP port 7800 and the devSrv process running on TCP port 7801 handle specially crafted long strings.
A remote attacker may trigger a crash or hang in the server and deny service to legitimate users. It should be noted that the application ships with a watchdog service that periodically restarts the services.
NSM 2004 FP2 and FP3 are reportedly vulnerable.
Affected Products:
- Juniper Networks NetScreen-Security Manager (NSM) 2004 FP2
- Juniper Networks NetScreen-Security Manager (NSM) 2004 FP3
