versions before 2.2100 for Perl accept replayed authentication responses via unverified nonce in server_step.\n\nserver_start generates a fresh nonce and sends it in the challenge, and nothing later compares that value against the nonce the client returns. server_step derives the expected digest from the client's own parameters, so a response verifies whenever its digest matches the nonce it carries. The count table it also checks is keyed on the client-supplied nonce and starts empty in each new server object, so a captured first response, carrying `nc=00000001`, passes that too. RFC 2831 defines the nonce in the response as the value the server sent in the preceding challenge.\n\nAn attacker who observes one successful `qop=auth` exchange can replay the captured response against a later session for the same service, host, realm and user, and authenticate as that user without knowing the password.", "title": "CVE description" } ], "product_status": { "recommended": [ "SUSE Linux Enterprise High Performance Computing 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server 12 SP5-LTSS:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch" ] }, "references": [ { "category": "external", "summary": "CVE-2026-86219", "url": "https://www.suse.com/security/cve/CVE-2026-86219" }, { "category": "external", "summary": "SUSE Bug 1279806 for CVE-2026-86219", "url": "https://bugzilla.suse.com/1279806" } ], "remediations": [ { "category": "vendor_fix", "details": "To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n", "product_ids": [ "SUSE Linux Enterprise High Performance Computing 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server 12 SP5-LTSS:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch" ] } ], "scores": [ { "cvss_v3": { "baseScore": 7.4, "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N", "version": "3.1" }, "products": [ "SUSE Linux Enterprise High Performance Computing 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server 12 SP5-LTSS:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch", "SUSE Linux Enterprise Server for SAP Applications 12 SP5:perl-Authen-SASL-0:2.16-5.6.1.noarch" ] } ], "threats": [ { "category": "impact", "date": "2026-09-22T08:32:16Z", "details": "important" } ], "title": "CVE-2026-86219" } ] }
