{"id":"CVE-2023-28098","summary":"OpenSIPS has vulnerability in the Digest Authentication Parser","details":"OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.7 and 3.2.4, a specially crafted Authorization header causes OpenSIPS to crash or behave in an unexpected way due to a bug in the function `parse_param_name()` . This issue was discovered while performing coverage guided fuzzing of the function parse_msg. The AddressSanitizer identified that the issue occurred in the function `q_memchr()` which is being called by the function `parse_param_name()`. This issue may cause erratic program behaviour or a server crash. It affects configurations containing\nfunctions that make use of the affected code, such as the function `www_authorize()` . Versions 3.1.7 and 3.2.4 contain a fix.","aliases":["GHSA-jrqg-vppj-hr2h"],"modified":"2026-09-09T08:15:13.262549Z","published":"2023-03-15T22:11:01.323Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-20"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28098.json"},"references":[{"type":"WEB","url":"https://opensips.org/pub/audit-2022/opensips-audit-technical-report-full.pdf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28098.json"},{"type":"ADVISORY","url":"https://github.com/OpenSIPS/opensips/security/advisories/GHSA-jrqg-vppj-hr2h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28098"},{"type":"FIX","url":"https://github.com/OpenSIPS/opensips/commit/dd9141b6f67d7df4072f3430f628d4b73df5e102"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opensips/opensips","events":[{"introduced":"0"},{"fixed":"c4122c9860458616cb438795c3545cd0f6014927"},{"introduced":"1e94abe8837fe3511fada132d67a6385d8d099a2"},{"fixed":"50407d34067f0e80765617c3bace78639e380d5a"},{"fixed":"dd9141b6f67d7df4072f3430f628d4b73df5e102"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.1.7"},{"introduced":"3.2.0"},{"fixed":"3.2.4"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:opensips:opensips:*:*:*:*:*:*:*:*"}}],"versions":["3.2.3","3.1.6","3.2.2","3.1.5","3.1.4","3.2.1","3.2.0","3.1.3","3.1.2","3.1.1","3.1.0","3.1.0-beta","2.1-rc1","2.1-alpha3","2.1-alpha2","2.1-alpha1","1.11.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-28098.json","vanir_signatures_modified":"2026-09-09T08:15:13Z","vanir_signatures":[{"source":"https://github.com/opensips/opensips/commit/dd9141b6f67d7df4072f3430f628d4b73df5e102","target":{"file":"parser/digest/param_parser.c"},"deprecated":false,"digest":{"line_hashes":["247547686598612213068219837690325280574","339647466155379564983535089726758936814","20315570940561390986620526790509945391","53474824694011475120748799657795201026","20491423859881481400958107825489552819","283484150145293206703144803414350910161","252623502418304526448774789455174779823","109893672161986706706081923443521176289","30216718607810163962715757758798610126","12240233011777167361664088998144800692","201580417574959593211344125302327996912","171362064333088177492798797453898410849","291653052331776195572336123584659661323","258650074668579419352872566805837387876","275818548259985119039085010443109055321","122502485359889279829409286630802667360","14468090916095836871965006952198700355","315210153695250302226530390161845931284","10693650291474013784854846233274895899","305668980067537824225729244611435617678","277395683851090530617402960294117551078","35593785104016004035201404059551337929","53474824694011475120748799657795201026","20491423859881481400958107825489552819","321042368468774142650088821421185208387","14862749958495557312098782723789999158","41349841758750015819809984058937759665","252429265025251340277365154050995207266","108426351532091590798468939681399267706","279892354978216646972129146177181208575","36187931180753271602796746117541314215","239944011417363052201845312281043376889","262260686294715753750764942815999954918","166109742917064330632270876188465747912","97227483754411719043153228167802643333","153415062438148035115129635132313152502","332732292118507171874284023830671419938","250883361808555070054302161561732859220"],"threshold":0.9},"id":"CVE-2023-28098-2ba83982","signature_type":"Line","signature_version":"v1"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
