Title

HAProxy信息泄露漏洞

Description

HAProxy是一款开源的TCP/HTTP负载均衡服务器。该服务器提供4层、7层代理，并能支持上万级别的连接，具有高效、稳定等特点。 HAProxy的‘buffer_slow_realign’函数存在安全漏洞，由于程序未能正确重组用于存放输出数据的缓冲区。远程攻击者利用该漏洞可通过发送特制的请求获取敏感信息（显示以前请求数据的未初始化的内存内容）。

CVE-2015-3281 (GCVE-0-2015-3281)

Vulnerability from cvelistv5 – Published: 2015-07-06 14:55 – Updated: 2024-08-06 05:39

Summary

The buffer_slow_realign function in HAProxy 1.5.x before 1.5.14 and 1.6-dev does not properly realign a buffer that is used for pending outgoing data, which allows remote attackers to obtain sensitive information (uninitialized memory contents of previous requests) via a crafted request.

Severity

No CVSS data available.
