Parameter Value
CVSS 5.3 (MEDIUM)
Type CWE-862 (Missing Authorization)
Vendor Cisa
Public PoC No

A deployment mode intended to expose only read access to a bundled packet-analysis component's interface denies a list of write-capable routes by pattern, but the pattern omits routes that modify tags attached to stored session records, and the proxy configuration otherwise permits the request method those routes use. This allows an authenticated user on a deployment intended to be read-only to add or remove tags on stored session records.
