{"id":"CVE-2005-2088","details":"The Apache HTTP server before 1.3.34, and 2.0.x before 2.0.55, when acting as an HTTP proxy, allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a \"Transfer-Encoding: chunked\" header and a Content-Length header, which causes Apache to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka \"HTTP Request Smuggling.\"","modified":"2026-01-27T04:06:03.112321Z","published":"2005-07-05T04:00:00Z","withdrawn":"2026-01-27T04:06:03.112321Z","references":[{"type":"ARTICLE","url":"http://marc.info/?l=apache-httpd-announce&m=112931556417329&w=3"},{"type":"REPORT","url":"http://seclists.org/lists/bugtraq/2005/Jun/0025.html"},{"type":"ADVISORY","url":"http://secunia.com/advisories/14530"},{"type":"ADVISORY","url":"http://secunia.com/advisories/17319"},{"type":"ADVISORY","url":"http://secunia.com/advisories/17487"},{"type":"ADVISORY","url":"http://secunia.com/advisories/17813"},{"type":"ADVISORY","url":"http://secunia.com/advisories/19072"},{"type":"ADVISORY","url":"http://secunia.com/advisories/19073"},{"type":"ADVISORY","url":"http://secunia.com/advisories/19185"},{"type":"ADVISORY","url":"http://secunia.com/advisories/19317"},{"type":"ADVISORY","url":"http://secunia.com/advisories/23074"},{"type":"EVIDENCE","url":"http://securityreason.com/securityalert/604"},{"type":"WEB","url":"http://securitytracker.com/id?1014323"},{"type":"ADVISORY","url":"http://slackware.com/security/viewer.php?l=slackware-security&y=2005&m=slackware-security.600000"},{"type":"ADVISORY","url":"http://support.avaya.com/elmodocs2/security/ASA-2006-081.htm"},{"type":"WEB","url":"http://www-1.ibm.com/support/search.wss?rs=0&q=PK13959&apar=only"},{"type":"WEB","url":"http://www-1.ibm.com/support/search.wss?rs=0&q=PK16139&apar=only"},{"type":"WEB","url":"http://www.apache.org/dist/httpd/CHANGES_1.3"},{"type":"WEB","url":"http://www.apache.org/dist/httpd/CHANGES_2.0"},{"type":"ARTICLE","url":"http://www.debian.org/security/2005/dsa-803"},{"type":"ARTICLE","url":"http://www.debian.org/security/2005/dsa-805"},{"type":"ADVISORY","url":"http://www.mandriva.com/security/advisories?name=MDKSA-2005:130"},{"type":"ADVISORY","url":"http://www.novell.com/linux/security/advisories/2005_18_sr.html"},{"type":"ADVISORY","url":"http://www.novell.com/linux/security/advisories/2005_46_apache.html"},{"type":"WEB","url":"http://www.redhat.com/support/errata/RHSA-2005-582.html"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/428138/100/0/threaded"},{"type":"WEB","url":"http://www.securityfocus.com/bid/14106"},{"type":"WEB","url":"http://www.securityfocus.com/bid/15647"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/usn-160-2"},{"type":"REPORT","url":"http://www.vupen.com/english/advisories/2005/2140"},{"type":"REPORT","url":"http://www.vupen.com/english/advisories/2005/2659"},{"type":"REPORT","url":"http://www.vupen.com/english/advisories/2006/0789"},{"type":"REPORT","url":"http://www.vupen.com/english/advisories/2006/1018"},{"type":"REPORT","url":"http://www.vupen.com/english/advisories/2006/4680"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/54a42d4b01968df1117cea77fc53d6beb931c0e05936ad02af93e9ac%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/5df9bfb86a3b054bb985a45ff9250b0332c9ecc181eec232489e7f79%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r0276683d8e1e07153fc8642618830ac0ade85b9ae0dc7b07f63bb8fc%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r2cb985de917e7da0848c440535f65a247754db8b2154a10089e4247b%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r5001ecf3d6b2bdd0b732e527654248abb264f08390045d30709a92f6%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r734a07156abf332d5ab27fb91d9d962cacfef4f3681e44056f064fa8%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r8828e649175df56f1f9e3919938ac7826128525426e2748f0ab62feb%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r9e8622254184645bc963a1d47c5d47f6d5a36d6f080d8d2c43b2b142%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/r9f93cf6dde308d42a9c807784e8102600d0397f5f834890708bf6920%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/rd65d8ba68ba17e7deedafbf5bb4899f2ae4dad781d21b931c2941ac3%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/re895fc1736d25c8cf57e102c871613b8aeec9ea26fd8a44e7942b5ab%40%3Ccvs.httpd.apache.org%3E"},{"type":"ARTICLE","url":"https://lists.apache.org/thread.html/rf6449464fd8b7437704c55f88361b66f12d5b5f90bcce66af4be4ba9%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11452"},{"type":"WEB","url":"https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A1237"},{"type":"WEB","url":"https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A1526"},{"type":"WEB","url":"https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A1629"},{"type":"WEB","url":"http
