Detailsinfo

A vulnerability classified as very critical has been found in Brocade SANnav. This affects an unknown code block of the component CLI Scripting. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Insufficient input sanitization of shell metacharacters in the Brocade SANnav CLI scripting component permits authenticated users to break out of restricted execution contexts on managed switches. An attacker with command execution permissions can leverage this flaw to run unauthorized shell commands across target fabric switches, bypassing command allow-lists and obtaining full administrative switch access. This vulnerability affects all Brocade SANnav versions before 3.0.1a.
