{"id":"CURL-CVE-2022-35252","summary":"control code in cookie denial of service","details":"When curl retrieves and parses cookies from an HTTP(S) server, it accepts\ncookies using control codes (byte values below 32). When cookies that contain\nsuch control codes are later sent back to an HTTP(S) server, it might make the\nserver return a 400 response. Effectively allowing a \"sister site\" to deny\nservice to siblings.","aliases":["CVE-2022-35252"],"modified":"2025-05-15T17:48:29Z","published":"2022-08-31T08:00:00Z","database_specific":{"issue":"https://hackerone.com/reports/1613943","CWE":{"id":"CWE-1286","desc":"Improper Validation of Syntactic Correctness of Input"},"URL":"https://curl.se/docs/CVE-2022-35252.json","affects":"both","last_affected":"7.84.0","severity":"Low","www":"https://curl.se/docs/CVE-2022-35252.html","package":"curl","award":{"currency":"USD","amount":"480"}},"affected":[{"ranges":[{"type":"SEMVER","events":[{"introduced":"4.9"},{"fixed":"7.85.0"}]},{"type":"GIT","repo":"https://github.com/curl/curl.git","events":[{"introduced":"ae1912cb0d494b48d514d937826c9fe83ec96c4d"},{"fixed":"8dfc93e573ca740544a2d79ebb0ed786592c65c3"}]}],"versions":["7.84.0","7.83.1","7.83.0","7.82.0","7.81.0","7.80.0","7.79.1","7.79.0","7.78.0","7.77.0","7.76.1","7.76.0","7.75.0","7.74.0","7.73.0","7.72.0","7.71.1","7.71.0","7.70.0","7.69.1","7.69.0","7.68.0","7.67.0","7.66.0","7.65.3","7.65.2","7.65.1","7.65.0","7.64.1","7.64.0","7.63.0","7.62.0","7.61.1","7.61.0","7.60.0","7.59.0","7.58.0","7.57.0","7.56.1","7.56.0","7.55.1","7.55.0","7.54.1","7.54.0","7.53.1","7.53.0","7.52.1","7.52.0","7.51.0","7.50.3","7.50.2","7.50.1","7.50.0","7.49.1","7.49.0","7.48.0","7.47.1","7.47.0","7.46.0","7.45.0","7.44.0","7.43.0","7.42.1","7.42.0","7.41.0","7.40.0","7.39.0","7.38.0","7.37.1","7.37.0","7.36.0","7.35.0","7.34.0","7.33.0","7.32.0","7.31.0","7.30.0","7.29.0","7.28.1","7.28.0","7.27.0","7.26.0","7.25.0","7.24.0","7.23.1","7.23.0","7.22.0","7.21.7","7.21.6","7.21.5","7.21.4","7.21.3","7.21.2","7.21.1","7.21.0","7.20.1","7.20.0","7.19.7","7.19.6","7.19.5","7.19.4","7.19.3","7.19.2","7.19.1","7.19.0","7.18.2","7.18.1","7.18.0","7.17.1","7.17.0","7.16.4","7.16.3","7.16.2","7.16.1","7.16.0","7.15.5","7.15.4","7.15.3","7.15.2","7.15.1","7.15.0","7.14.1","7.14.0","7.13.2","7.13.1","7.13.0","7.12.3","7.12.2","7.12.1","7.12.0","7.11.2","7.11.1","7.11.0","7.10.8","7.10.7","7.10.6","7.10.5","7.10.4","7.10.3","7.10.2","7.10.1","7.10","7.9.8","7.9.7","7.9.6","7.9.5","7.9.4","7.9.3","7.9.2","7.9.1","7.9","7.8.1","7.8","7.7.3","7.7.2","7.7.1","7.7","7.6.1","7.6","7.5.2","7.5.1","7.5","7.4.2","7.4.1","7.4","7.3","7.2.1","7.2","7.1.1","7.1","6.5.2","6.5.1","6.5","6.4","6.3.1","6.3","6.2","6.1","6.0","5.11","5.10","5.9.1","5.9","5.8","5.7.1","5.7","5.5.1","5.5","5.4","5.3","5.2.1","5.2","5.0","4.10","4.9"],"database_specific":{"source":"https://curl.se/docs/CURL-CVE-2022-35252.json","vanir_signatures":[{"deprecated":false,"id":"CURL-CVE-2022-35252-40001950","target":{"file":"lib/cookie.c","function":"Curl_cookie_add"},"source":"https://github.com/curl/curl.git/commit/8dfc93e573ca740544a2d79ebb0ed786592c65c3","signature_version":"v1","digest":{"function_hash":"101577549221486820251477540902575052938","length":10270},"signature_type":"Function"},{"deprecated":false,"id":"CURL-CVE-2022-35252-da8e59b2","target":{"file":"lib/cookie.c"},"source":"https://github.com/curl/curl.git/commit/8dfc93e573ca740544a2d79ebb0ed786592c65c3","signature_version":"v1","digest":{"threshold":0.9,"line_hashes":["207174381781505439734157797208570689465","323636526016408636056947651169731239107","41658588875721786792075652302982925883","337712700965789756139547950839555361827","324553776354522457928145933274234757672","166785840259375890878085619707189037138","77198963250350460702192797698770123794"]},"signature_type":"Line"}]}}],"schema_version":"1.7.3","credits":[{"name":"Axel Chong","type":"FINDER"},{"name":"Daniel Stenberg","type":"REMEDIATION_DEVELOPER"}]}
