[原文]The IP cloaking feature (cloak.c) in UnrealIRCd 3.2, and possibly other versions, uses a weak hashing scheme to hide IP addresses, which could allow remote attackers to use brute force methods to gain other user's IP addresses.


[CNNVD]Unreal IRCD Cloak.C IP地址泄露漏洞(CNNVD-200408-031)

        UnrealIRCd 3.2或其他可能版本的IP伪装功能存在漏洞。该漏洞采用弱散列计划隐藏IP地址。远程攻击者使用暴力的方法来获得其他用户的IP地址。

UnrealIRCd IP Cloaking Weakness Information Disclosure
Remote / Network Access Cryptographic, Information Disclosure
Loss of Confidentiality
Exploit Public

- 漏洞描述

UnrealIRCd contains a flaw that may lead to an unauthorized IP information disclosure.  The issue is due to the weakIP cloaking algorithm, which is intended to prevent IP bruteforce. By knowning one plaintext and hashed IP address and another hashed IP address, a remote attacker can recover the keys of several IRC networks and get the IP addresses, resulting in a loss of confidentiality.

- 漏洞讨论

Unreal ircd is reported prone to a vulnerability that may allow a remote attacker to disclose a user's IP address when the IP cloaking feature is used to obfuscate the IP address. It is reported that due to a weakness in the algorithm used to cloak IP addresses in the 'cloak.c' file, an attacker can disclose a user's IP address.

Successful exploitation of this issue will reveal the IP address of a vulnerable user and the attacker can then carry out other attacks against the computer.

- 漏洞利用

The researchers who discovered this vulnerability have developed exploit code to carry out this attack. This exploit has not been released to public.

- 解决方案

Unreal ircd 3.2.1 is available to address this issue.
