{“lastseen”:””,”description”:”If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request for a realm matching a DNS zone where they created SRV records pointing to arbitrary ports and hostnames (which may resolve to loopback or internal IP addresses). This vulnerability can be exploited to probe internal network topology and firewall rules, perform port scanning, and exfiltrate data. Deployments where\\nthe \\”use_dns\\” setting is explicitly set to false are not affected.”,”published”:”2025-11-12T16:35:27.877Z”,”modified”:”2025-11-12T21:07:09.379Z”,”type”:”cve”,”title”:”Python-kdcproxy: unauthenticated ssrf via realm\u2011controlled dns srv”,”source”:”redhat”,”references”:”https:\/\/access.redhat.com\/security\/cve\/CVE-2025-59088\\nhttps:\/\/bugzilla.redhat.com\/show_bug.cgi?id=2393955\\nhttps:\/\/github.com\/latchset\/kdcproxy\/pull\/68″,”id”:”CVE-2025-59088″,”bulletinFamily”:””,”cwe”:[“CWE-918″],”cvelist”:null,”sourceData”:””,”sourceHref”:””,”cvss”:{“score”:8.6,”severity”:”HIGH”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:N\/UI:N\/S:C\/C:H\/I:N\/A:N”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Red Hat Enterprise Linux 10″,”version”:””,”vendor”:”Red Hat”,”ai_description”:”Server-side request forgery vulnerability in kdcproxy via realm-controlled DNS SRV records, allowing attackers to probe internal network topology and exfiltrate data.”,”ai_severity”:”High”,”ai_vendor”:”Red Hat”,”ai_product”:”kdcproxy”,”ai_version”:””,”ai_score”:8.6}<\/p>\n","protected":false},"excerpt":{"rendered":"
