CVSS: 5.3EPSS: 0%CPEs: 8EXPL: 6CVE-2023-51764 – postfix: SMTP smuggling vulnerability
https://notcve.org/view.php?id=CVE-2023-51764
Postfix through 3.8.5 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions). Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack variants (by always disallowing <LF> without <CR>), a different solution is required, such as the smtpd_forbid_bare_newline=yes option with a Postfix minimum version of 3.5.23, 3.6.13, 3.7.9, 3.8.4, or 3.9. • https://github.com/duy-31/CVE-2023-51764 https://github.com/eeenvik1/CVE-2023-51764 https://github.com/Double-q1015/CVE-2023-51764 https://github.com/d4op/CVE-2023-51764-POC http://www.openwall.com/lists/oss-security/2023/12/24/1 http://www.openwall.com/lists/oss-security/2023/12/25/1 http://www.openwall.com/lists/oss-security/2024/05/09/3 https://access.redhat.com/security/cve/CVE-2023-51764 https://bugzilla.redhat.com/show_bug.cgi?id=2255563 http • CWE-345: Insufficient Verification of Data Authenticity CWE-451: User Interface (UI) Misrepresentation of Critical Information •

https://notcve.org/view.php?id=CVE-2017-10140
Postfix before 2.11.10, 3.0.x before 3.0.10, 3.1.x before 3.1.6, and 3.2.x before 3.2.2 might allow local users to gain privileges by leveraging undocumented functionality in Berkeley DB 2.x and later, related to reading settings from DB_CONFIG in the current directory. Postfix, en versiones anteriores a la 2.11.10, versiones 3.0.x anteriores a la 3.0.10, versiones 3.1.x anteriores a la 3.1.6 y versiones 3.2.x anteriores a la 3.2.2, podría permitir que usuarios locales obtengan privilegios aprovechando una funcionalidad no documentada en Berkeley DB, en versiones 2.x y posteriores.

Multiple SQL injection vulnerabilities in Postfix Admin (aka postfixadmin) before 2.3.5 allow remote authenticated users to execute arbitrary SQL commands via (1) the pw parameter to the pacrypt function, when mysql_encrypt is configured, or (2) unspecified vectors that are used in backup files generated by backup.php. Múltiples vulnerabilidades de inyección SQL en Postfix Admin (también conocido como postfixadmin) anterior a 2.3.5 permiten a usuarios remotos autenticados ejecutar comandos SQL a través de (1) el parámetro pw en la función pacrypt, cuando mysql_encrypt está configurado, o (2) vectores no especificados que se utilizan en los ficheros de las copias de seguridad generados por backup.php. • http://www.codseq.it/advisories/multiple_vulnerabilities_in_postfixadmin http://www.openwall.com/lists/oss-security/2012/01/26/5 http://www.openwall.com/lists/oss-security/2012/01/27/5 http://www.securityfocus.com/bid/51680 https://svn.code.sf.net/p/postfixadmin/code/branches/postfixadmin-2.3/CHANGELOG.TXT • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •

The SMTP server in Postfix before 2.5.13, 2.6.x before 2.6.10, 2.7.x before 2.7.4, and 2.8.x before 2.8.3, when certain Cyrus SASL authentication methods are enabled, does not create a new server handle after client authentication fails, which allows remote attackers to cause a denial of service (heap memory corruption and daemon crash) or possibly execute arbitrary code via an invalid AUTH command with one method followed by an AUTH command with a different method. El servidor SMTP en Postfix anterior a v2.5.13, v2.6.x anterior a v2.6.10, v2.7.x anterior a v2.7.4, y v2.8.x anterior a v2.8.3, cuando ciertos métodos Cyrus SASL de autenticación son activados, no crea un nuevo manejador de servidor después de que la autentificación falle, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria libre y caída de demonio) o posiblemente ejecutar código de su elección a tra´ves de un comando AUTH no válido con un método seguido por un comando AUTH con un método diferente. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://lists.opensuse.org/opensuse-security-announce/2011-05/msg00002.html http://secunia.com/advisories/44500 http://security.gentoo.org/glsa/glsa-201206-33.xml http://securityreason.com/securityalert/8247 http://www.debian.org/security/2011/dsa-2233 http://www.kb.cert.org/vuls/id/727230 http://www.mail-archive.com/postfix-announce%40postfix.org/msg00007.html http://www.mandriva.com/security/advisories?name=MDVSA-2011 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Postfix before 2.3.15, 2.4 before 2.4.8, 2.5 before 2.5.4, and 2.6 before 2.6-20080814, when the operating system supports hard links to symlinks, allows local users to append e-mail messages to a file to which a root-owned symlink points, by creating a hard link to this symlink and then sending a message. NOTE: this can be leveraged to gain privileges if there is a symlink to an init script.
