In Apache James, using Jazzer fuzzer, we identified that an IMAP user can craft IMAP LIST commands to orchestrate a Denial Of Service using a vulnerable Regular expression. This affected Apache James prior to 3.6.1 We recommend upgrading to Apache James 3.6.1 or higher , which enforce the use of RE2J regular expression engine to execute regex in linear time without back-tracking. En Apache James, usando Jazzer fuzzer, identificamos que un usuario de IMAP puede diseñar comandos IMAP LIST para orquestar una denegación de servicio usando una expresión regular vulnerable. Esto afectaba a Apache James versiones anteriores a 3.6.1. Recomendamos actualizar a Apache James versión 3.6.1 o superior, que refuerza el uso del motor de expresiones regulares RE2J para ejecutar regex en tiempo lineal sin retroceso • http://www.openwall.com/lists/oss-security/2022/01/04/2 https://www.openwall.com/lists/oss-security/2022/01/04/2 •

Apache James prior to release 3.6.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command. This can result in Man-in -the-middle command injection attacks, leading potentially to leakage of sensible information. Apache James versiones anteriores a 3.6.1, es vulnerable a un ataque de buffering que es basado en el uso del comando STARTTLS. Esto puede resultar en ataques de inyección de comandos de tipo "Man-in-the-middle", conllevando potencialmente a un filtrado de información confidencial • http://www.openwall.com/lists/oss-security/2022/01/04/1 http://www.openwall.com/lists/oss-security/2022/09/20/1 https://www.openwall.com/lists/oss-security/2022/01/04/1 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

Apache PDFBox 2.0.14 does not properly initialize the XML parser, which allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted XFDF. Apache PDFBox versión 2.0.14 no inicializa correctamente el analizador XML, lo que permite a los atacantes dependientes del contexto realizar ataques de Entidades Externas XML (XXE) por medio de un XFDF creado. • https://lists.apache.org/thread.html/1a3756557f8cb02790b7183ccf7665ae23f608a421c4f723113bca79%40%3Cusers.pdfbox.apache.org%3E https://lists.apache.org/thread.html/8a19bd6d43e359913341043c2a114f91f9e4ae170059539ad1f5673c%40%3Ccommits.tika.apache.org%3E https://lists.apache.org/thread.html/bc8db1bf459f1ad909da47350ed554ee745abe9f25f2b50cad4e06dd%40%3Cserver-dev.james.apache.org%3E https://lists.apache.org/thread.html/be86fcd7cd423a3fe6b73a3cb9d7cac0b619d0deb99e6b5d172c98f4%40%3Ccommits.tika.apache.org%3E https://lists.apache.org/thread.html/r0a2141abeddae66dd57025f1681c8425834062b7c0c7e0b1d830a95d&# • CWE-611: Improper Restriction of XML External Entity Reference •

The JMX server embedded in Apache James, also used by the command line client is exposed to a java de-serialization issue, and thus can be used to execute arbitrary commands. As James exposes JMX socket by default only on local-host, this vulnerability can only be used for privilege escalation. Release 3.0.1 upgrades the incriminated library. El servidor JMX embebido en Apache James, también empleado por el cliente de línea de comandos, está expuesto a un problema de deserialización de Java, por lo que puede emplearse para ejecutar comandos arbitrarios. Debido a que James expone el socket JMP por defecto sólo en local-host, esta vulnerabilidad solo puede emplearse para escalar privilegios. • http://www.securityfocus.com/bid/101532 https://www.mail-archive.com/server-user%40james.apache.org/msg15633.html • CWE-502: Deserialization of Untrusted Data •

Apache James Server 2.3.2, when configured with file-based user repositories, allows attackers to execute arbitrary system commands via unspecified vectors. Apache James Server 2.3.2, cuando se configura con repositorios de usuario basados en archivos, permite a atacantes ejecutar comandos de sistema arbitrarios a través de vectores no especificados. • https://www.exploit-db.com/exploits/48130 http://packetstormsecurity.com/files/133798/Apache-James-Server-2.3.2-Arbitrary-Command-Execution.html http://packetstormsecurity.com/files/156463/Apache-James-Server-2.3.2-Insecure-User-Creation-Arbitrary-File-Write.html http://www.openwall.com/lists/oss-security/2015/09/30/7 http://www.openwall.com/lists/oss-security/2015/10/01/2 http://www.securityfocus.com/archive/1/536575/100/0/threaded https://blogs.apache.org/james/entry/apache_jame • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
