In certain configurations using RewriteRule with proxy flag or ProxyPassMatch, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker. Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow. An additional exposure was found when using mod_proxy in reverse proxy mode. In certain configurations using RewriteRule with proxy flag or ProxyPassMatch, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker. A flaw was found in mod_log_config.

In certain reverse proxy configurations using the ProxyPassMatch directive or using the RewriteRule directive with the [P] flag, a remote attacker could make the proxy connect to an arbitrary server. This could allow the attacker to access internal servers that are not otherwise accessible from the outside. The three CVE ids denote slightly different variants of the same issue. Note that, even with this issue fixed, it is the responsibility of the administrator to ensure that the regular expression replacement pattern for the target URI does not allow a client to append arbitrary strings to the host or port parts of the target URI. For example, the configuration ProxyPassMatch ^/mail(.*) http://internal-host$1 is still insecure and should be replaced by one of the following configurations : ProxyPassMatch ^/mail(/.*) http://internal-host$1 ProxyPassMatch ^/mail/(.*) http://internal-host/$1 - CVE-2012-0031 : An apache2 child process could cause the parent process to crash during shutdown. This is a violation of the privilege separation between the apache2 processes and could potentially be used to worsen the impact of other vulnerabilities. - CVE-2012-0053 : The response message for error code 400 (bad request) could be used to expose last seen 2020-03-17 modified 2012-02-07 plugin id 57851 published 2012-02-07 reporter This script is Copyright (C) 2012-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/57851 title Debian DSA-2405-1 : apache2 - multiple issues NASL family Fedora Local Security Checks NASL id FEDORA_2012-1642.NASL description This update contains the latest stable release of the Apace HTTP Server, version 2.2.22.

| description | BUGTRAQ ID: 50494 CVE ID: CVE-2011-3607 Apache HTTP Server是Apache软件基金会的一个开放源代码的网页服务器，可以在大多数电脑操作系统中运行，由于其跨平台和安全性被广泛使用，是最流行的Web服务器端软件之一。 Apache HTTP Server在"ap_pregsub()"函数的实现上存在本地权限提升漏洞，本地攻击者可利用此漏洞以提升的权限执行任意代码。 要触发此漏洞，需要启用mod_setenvif，并且攻击者可以在受影响服务器中放置恶意的.htaccess文件。此漏洞源于 "ap_pregsub()" 函数 (server/utils.c) 中的整数溢出错误，通过特制的.htaccess文件可造成堆缓冲区溢出。 Apache HTTP Server 2.2.x Apache HTTP Server 2.0.x 厂商补丁： Apache Group ------------ 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： http://httpd.apache.org/ |
