{"id":"CVE-2011-3368","details":"The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character.","modified":"2026-01-27T04:10:56.191621Z","published":"2011-10-05T22:55:02Z","withdrawn":"2026-01-27T04:10:56.191621Z","related":["openSUSE-SU-2024:10268-1"],"references":[{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2012-0542.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2012-0543.html"},{"type":"ADVISORY","url":"http://secunia.com/advisories/46288"},{"type":"ADVISORY","url":"http://secunia.com/advisories/46414"},{"type":"ADVISORY","url":"http://secunia.com/advisories/48551"},{"type":"ADVISORY","url":"http://www.debian.org/security/2012/dsa-2405"},{"type":"ADVISORY","url":"http://www.mandriva.com/security/advisories?name=MDVSA-2011:144"},{"type":"ADVISORY","url":"http://www.mandriva.com/security/advisories?name=MDVSA-2013:150"},{"type":"ARTICLE","url":"http://www.contextis.com/research/blog/reverseproxybypass/"},{"type":"FIX","url":"http://web.archiveorange.com/archive/v/ZyS0hzECD5zzb2NkvQlt"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=740045"},{"type":"FIX","url":"http://svn.apache.org/viewvc?view=revision&revision=1179239"},{"type":"WEB","url":"http://kb.juniper.net/JSA10585"},{"type":"WEB","url":"http://lists.apple.com/archives/security-announce/2012/Sep/msg00004.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2011-11/msg00011.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-updates/2013-02/msg00009.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-updates/2013-02/msg00012.html"},{"type":"WEB","url":"http://marc.info/?l=bugtraq&m=133294460209056&w=2"},{"type":"WEB","url":"http://marc.info/?l=bugtraq&m=134987041210674&w=2"},{"type":"WEB","url":"http://osvdb.org/76079"},{"type":"WEB","url":"http://seclists.org/fulldisclosure/2011/Oct/232"},{"type":"WEB","url":"http://seclists.org/fulldisclosure/2011/Oct/273"},{"type":"WEB","url":"http://support.apple.com/kb/HT5501"},{"type":"WEB","url":"http://www-01.ibm.com/support/docview.wss?uid=nas2064c7e5f53452ff686257927003c8d42"},{"type":"WEB","url":"http://www-01.ibm.com/support/docview.wss?uid=nas2b7c57b1f1035675186257927003c8d48"},{"type":"WEB","url":"http://www.exploit-db.com/exploits/17969"},{"type":"WEB","url":"http://www.oracle.com/technetwork/topics/security/cpujan2015-1972971.html"},{"type":"WEB","url":"http://www.oracle.com/technetwork/topics/security/cpujul2012-392727.html"},{"type":"WEB","url":"http://www.redhat.com/support/errata/RHSA-2011-1391.html"},{"type":"WEB","url":"http://www.redhat.com/support/errata/RHSA-2011-1392.html"},{"type":"WEB","url":"http://www.securityfocus.com/bid/49957"},{"type":"WEB","url":"http://www.securitytracker.com/id?1026144"},{"type":"WEB","url":"https://exchange.xforce.ibmcloud.com/vulnerabilities/70336"},{"type":"WEB","url":"https://lists.apache.org/thread.html/54a42d4b01968df1117cea77fc53d6beb931c0e05936ad02af93e9ac%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/5df9bfb86a3b054bb985a45ff9250b0332c9ecc181eec232489e7f79%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/8d63cb8e9100f28a99429b4328e4e7cebce861d5772ac9863ba2ae6f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/f7f95ac1cd9895db2714fa3ebaa0b94d0c6df360f742a40951384a53%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r0276683d8e1e07153fc8642618830ac0ade85b9ae0dc7b07f63bb8fc%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r064df0985779b7ee044d3120d71ba59750427cf53f57ba3384e3773f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r1d201e3da31a2c8aa870c8314623caef7debd74a13d0f25205e26f15%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r2cb985de917e7da0848c440535f65a247754db8b2154a10089e4247b%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r5419c9ba0951ef73a655362403d12bb8d10fab38274deb3f005816f5%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r57608dc51b79102f3952ae06f54d5277b649c86d6533dcd6a7d201f7%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r5f9c22f9c28adbd9f00556059edc7b03a5d5bb71d4bb80257c0d34e4%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r688df6f16f141e966a0a47f817e559312b3da27886f59116a94b273d%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r75cbe9ea3e2114e4271bbeca7aff96117b50c1b6eb7c4772b0337c1f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r8828e649175df56f1f9e3919938ac7826128525426e2748f0ab62feb%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9e8622254184645bc963a1d47c5d47f6d5a36d6f080d8d2c43b2b142%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://list
