Descriptions

VMware SpringSource Spring Framework before 2.5.6.SEC03, 2.5.7.SR023, and 3.x before 3.0.6, when a container supports Expression Language (EL), evaluates EL expressions in tags twice, which allows remote attackers to obtain sensitive information via a (1) name attribute in a (a) spring:hasBindErrors tag; (2) path attribute in a (b) spring:bind or (c) spring:nestedpath tag; (3) arguments, (4) code, (5) text, (6) var, (7) scope, or (8) message attribute in a (d) spring:message or (e) spring:theme tag; or (9) var, (10) scope, or (11) value attribute in a (f) spring:transform tag, aka "Expression Language Injection."

VMware SpringSource Spring Framework anterior a v2.5.6.SEC03, v2.5.7.SR023, y v3.x anterior a v3.0.6, cuando el contenedor soporta Expression Language (EL), evalúa expresiones EL en etiquetas, permite a atacantes remotos obtener información sensible mediante (1) el atributo name en a (a) spring:hasBindErrors; (2) el atributo path en a (b) spring:bind o (c) spring:nestedpath; (3) arguments, (4) code, (5) text, (6) var, (7) scope, o (8) atributo message in a (d) spring:message o (e) spring:theme; or (9) var, (10) scope, or (11) atributo value en a (f) spring:transform, también conocido como "Inyección de Expresión de Lenguaje"

Red Hat JBoss Portal is the open source implementation of the Java EE suite of services and Portal services running atop Red Hat JBoss Enterprise Application Platform. JBoss Web Services leaked side-channel data when distributing symmetric keys, allowing a remote attacker to recover the entire plain text form of a symmetric key. Spring framework could possibly evaluate Expression Language expressions twice, allowing a remote attacker to execute arbitrary code in the context of the application server, or to obtain sensitive information from the server.
