{"id":"CVE-2021-28164","details":"In Eclipse Jetty 9.4.37.v20210219 to 9.4.38.v20210224, the default compliance mode allows requests with URIs that contain %2e or %2e%2e segments to access protected resources within the WEB-INF directory. For example a request to /context/%2e/WEB-INF/web.xml can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application.","aliases":["GHSA-v7ff-8wcx-gmc5"],"modified":"2026-04-10T04:31:39.843074Z","published":"2021-04-01T15:15:14.157Z","related":["GHSA-v7ff-8wcx-gmc5","SUSE-SU-2021:2005-1","openSUSE-SU-2021:2005-1","openSUSE-SU-2024:10878-1"],"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/r3c55b0baa4dc38958ae147b2f216e212605f1071297f845e14477d36%40%3Cissues.zookeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbc075a4ac85e7a8e47420b7383f16ffa0af3b792b8423584735f369f%40%3Cissues.solr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rcea249eb7a0d243f21696e4985de33f3780399bf7b31ea1f6d489b8b%40%3Cissues.zookeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r111f1ce28b133a8090ca4f809a1bdf18a777426fc058dc3a16c39c66%40%3Cissues.solr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r4b1fef117bccc7f5fd4c45fd2cabc26838df823fe5ca94bc42a4fd46%40%3Cissues.ignite.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r6ac9e263129328c0db9940d72b4a6062e703c58918dd34bd22cdf8dd%40%3Cissues.ignite.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r780c3c210a05c5bf7b4671303f46afc3fe56758e92864e1a5f0590d0%40%3Cjira.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r7dd079fa0ac6f47ba1ad0af98d7d0276547b8a4e005f034fb1016951%40%3Cissues.zookeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r90e7b4c42a96d74c219e448bee6a329ab0cd3205c44b63471d96c3ab%40%3Cissues.zookeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9974f64723875052e02787b2a5eda689ac5247c71b827d455e5dc9a6%40%3Cissues.solr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd0471252aeb3384c3cfa6d131374646d4641b80dd313e7b476c47a9c%40%3Cissues.solr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r0841b06b48324cfc81325de3c05a92e53f997185f9d71ff47734d961%40%3Cissues.solr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r2a3ea27cca2ac7352d392b023b72e824387bc9ff16ba245ec663bdc6%40%3Cissues.zookeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r5b3693da7ecb8a75c0e930b4ca26a5f97aa0207d9dae4aa8cc65fe6b%40%3Cissues.ignite.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r8e6c116628c1277c3cf132012a66c46a0863fa2a3037c0707d4640d4%40%3Cissues.zookeeper.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd7c8fb305a8637480dc943ba08424c8992dccad018cd1405eb2afe0e%40%3Cdev.ignite.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r2ea2f0541121f17e470a0184843720046c59d4bde6d42bf5ca6fad81%40%3Cissues.solr.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r4a66bfbf62281e31bc1345ebecbfd96f35199eecd77bfe4e903e906f%40%3Cissues.ignite.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r763840320a80e515331cbc1e613fa93f25faf62e991974171a325c82%40%3Cdev.zookeeper.apache.org%3E"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210611-0006/"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"ADVISORY","url":"https://github.com/eclipse/jetty.project/security/advisories/GHSA-v7ff-8wcx-gmc5"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"},{"type":"EVIDENCE","url":"http://packetstormsecurity.com/files/164590/Jetty-9.4.37.v20210219-Information-Disclosure.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jetty/jetty.project","events":[{"introduced":"0"},{"last_affected":"27afab2bd37780d179836e313e0fe11bc4fa0ce9"},{"introduced":"0"},{"last_affected":"288f3cc74549e8a913bf363250b0744f2695b8e6"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"9.4.37-20210219"},{"introduced":"0"},{"last_affected":"9.4.38-20210224"}]}}],"versions":["jetty-8.0.0.RC0","jetty-8.1.0.RC0","jetty-9.1.0.M0","jetty-9.1.0.RC0","jetty-9.1.0.RC1","jetty-9.1.0.RC2","jetty-9.1.0.v20131115","jetty-9.1.1.v20140108","jetty-9.1.2.v20140210","jetty-9.1.3.v20140225","jetty-9.1.4.v20140401","jetty-9.2.0.M0","jetty-9.2.0.M1","jetty-9.2.0.RC0","jetty-9.2.0.v20140523","jetty-9.2.0.v20140526","jetty-9.2.1.v20140609","jetty-9.4.10.v20180503","jetty-9.4.12.v20180830","jetty-9.4.13.v20181111","jetty-9.4.14.v20181114","jetty-9.4.15.v20190215","jetty-9.4.2.v20170220","jetty-9.4.26.v20200117","jetty-9.4.27.v20200227","jetty-9.4.28.v20200408","jetty-9.4.32.v20200930","jetty-9.4.36.v20210114","jetty-9.4.37.v20210219","jetty-9.4.38.v20210224","jetty-9.4.6.v20170531"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-28164.json","unresolved_ranges":[{"events":[{"introduced":"11.0"},{"last_affected":"11.70.1"}]},{"events":[
