CVE-2026-85490: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Brocade Brocade Active Support Connectivity Gateway
Description
CVE-2026-85490 is a path traversal vulnerability in Brocade Active Support Connectivity Gateway versions before 3.5.0. The application does not properly sanitize path traversal sequences in support bundle archives ingested from remote endpoints. This allows an unauthenticated remote attacker to write arbitrary files to restricted locations on the host, potentially enabling remote code execution.

Technical Analysis
Brocade Active Support Connectivity Gateway (ASCG) versions prior to 3.5.0 fail to sanitize path traversal sequences in archive entries of support bundles ingested from remote compromised endpoints. An unauthenticated attacker who can send or intercept these archives can exploit this flaw to write arbitrary files outside the intended extraction directory. This improper limitation of pathname to a restricted directory (CWE-22) can lead to remote code execution on the underlying host system.
Potential Impact
An unauthenticated remote attacker can leverage this vulnerability to write arbitrary files to restricted locations on the host system, potentially leading to remote code execution. This compromises the confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
A fix is available in Brocade Active Support Connectivity Gateway version 3.5.0 and later. Users should upgrade to version 3.5.0 or above to remediate this vulnerability. No vendor advisory content was provided to indicate alternative mitigations or temporary fixes. Patch status is confirmed by the version boundary in the affectedVersions field.
