Description

Description

Cisco Security Manager is prone to a command-execution vulnerability. Attackers can exploit this issue to execute arbitrary commands within the context of the affected device. Failed exploit attempts may result in a denial-of-service condition. This issue is tracked by Cisco Bug ID CSCvj29055.

Technologies Affected

  • Cisco Security Manager 4.11.0 SP2 P1
  • Cisco Security Manager 4.12
  • Cisco Security Manager 4.13
  • Cisco Security Manager 4.14(0)SP2
  • Cisco Security Manager 4.14(0.131)
  • Cisco Security Manager 4.17(0.77)

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Implement multiple redundant layers of security.
Memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
