CVE-2014-0050 – Apache Commons FileUpload and Apache Tomcat - Denial of Service

https://notcve.org/view.php?id=CVE-2014-0050

MultipartStream.java in Apache Commons FileUpload before 1.3.1, as used in Apache Tomcat, JBoss Web, and other products, allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted Content-Type header that bypasses a loop's intended exit conditions. MultipartStream.java en Apache Commons FileUpload anterior a 1.3.1, utilizado en Apache Tomcat, JBoss Web y otros productos, permite a atacantes remotos causar una denegación de servicio (bucle infinito y consumo de CPU) a través de una cabecera Content-Type manipulada que evade las condiciones de salida del bucle. A denial of service flaw was found in the way Apache Commons FileUpload, which is embedded in Tomcat and JBoss Web, handled small-sized buffers used by MultipartStream. A remote attacker could use this flaw to create a malformed Content-Type header for a multipart request, causing Tomcat to enter an infinite loop when processing such an incoming request. • https://www.exploit-db.com/exploits/31615 http://advisories.mageia.org/MGASA-2014-0110.html http://blog.spiderlabs.com/2014/02/cve-2014-0050-exploit-with-boundaries-loops-without-boundaries.html http://jvn.jp/en/jp/JVN14876762/index.html http://jvndb.jvn.jp/jvndb/JVNDB-2014-000017 http://mail-archives.apache.org/mod_mbox/commons-dev/201402.mbox/%3C52F373FC.9030907%40apache.org%3E http://marc.info/?l=bugtraq&m=143136844732487&w=2 http://packetstormsecurity.com/files/127215/VMware& • CWE-264: Permissions, Privileges, and Access Controls •
