In IP Multimedia Subsystem, there is a possible authentication bypass due to a logic error in the code.
In IP Multimedia Subsystem, there is a possible authentication bypass due to a logic error in the code. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
