CVE-2010-1870

La capacidad OGNL extensive expression evaluation en XWork de Struts v2.0.0 hasta v2.1.8.1, como el usado en Atlassian Fisheye, Crucible,y posiblemente otros productos, usa una lista blanca permisiva, la cual permite a atacantes remotos modificar los objetos del contexto del lado del servidor y evitar el mecanismo de protección "#" en ParameterInterceptors a través de (1) #context, (2) #_memberAccess, (3) #root, (4) #this, (5) #_typeResolver, (6) #_classResolver, (7) #_traceEvaluations, (8) #_lastEvaluation, (9) #_keepLastEvaluation, y posiblemente otras variables de contexto OGNL, una vulnerabilidad diferente de CVE-2008-6504.

Multiple Cisco products include an implementation of the Apache Struts 2 component that is affected by a remote command execution vulnerability identified by Apache with Common Vulnerabilities and Exposures ID CVE-2010-1870. The vulnerability is due to insufficient sanitization on user-supplied input in the XWorks component of the affected software. The component uses the ParameterInterceptors directive to parse the Object-Graph Navigation Language (OGNL) expressions that are implemented via a whitelist feature. An attacker could exploit this vulnerability by sending crafted requests that contain OGNL expressions to an affected system. An exploit could allow the attacker to execute arbitrary code on the targeted system. Cisco has released free software updates that address this vulnerability for all the affected products except Cisco Business Edition 3000 Series. Customers using Cisco Business Edition 3000 Series should contact their Cisco representative for available options.
