CVSS: 7.5EPSS: 97%CPEs: 31EXPL: 2CVE-2020-8617 – A logic error in code which checks TSIG validity can be used to trigger an assertion failure in tsig.c
https://notcve.org/view.php?id=CVE-2020-8617
Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. Since BIND, by default, configures a local session key even on servers whose configuration does not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately exits. Prior to the introduction of the check the server would continue operating in an inconsistent state, with potentially harmful results. Al usar un mensaje especialmente diseñado, un atacante puede causar que un servidor BIND alcance un estado inconsistente si el atacante conoce (o adivina con éxito) el nombre de una clave TSIG utilizada por el servidor. • https://www.exploit-db.com/exploits/48521 https://github.com/knqyf263/CVE-2020-8617 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html http://packetstormsecurity.com/files/157836/BIND-TSIG-Denial-Of-Service.html http://www.openwall.com/lists/oss-security/2020/05/19/4 https://kb.isc.org/docs/cve-2020-8617 https://lists.debian.org/debian-lts-announce/2020/05/msg00031.html https:/ • CWE-617: Reachable Assertion •
