Description:
bartavelle has reported a weakness in UnrealIRCd, which can be exploited by malicious users to bypass certain security features.

The issue is caused due to the use of a weak IP cloaking algorithm and can be exploited to gain knowledge of other users' IP addresses.

Successful exploitation requires knowledge of a clear text IP address and two hashed IP addresses.

Version 3.2 has been reported vulnerable. Prior versions may also be affected.
