IBM Spectrum Protect Operations Center 7.1 and 8.1 is vulnerable to a denial of service, caused by a RPC that allows certain cache values to be set and dumped to a file. By setting a grossly large cache value and dumping that cached value to a file multiple times, a remote attacker could exploit this vulnerability to cause the consumption of all memory resources. IBM X-Force ID: 192156.

Weakness

The product does not properly control the allocation and maintenance of a limited resource.

Affected Software

Name Vendor Start Version End Version
Spectrum_protect_operations_center Ibm 7.1.0.000 (including) 7.1.13.000 (excluding)
Spectrum_protect_operations_center Ibm 8.1.0.000 (including) 8.1.10.200 (excluding)

Potential Mitigations

  • Mitigation of resource exhaustion attacks requires that the target system either:

  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.

  • The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
