|Article Summary||Security vulnerability on AAOP for VMware SpringSource Spring Framework (CVE -2011-2730). 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."|

|Alert Impact||Not Applicable|
|Technical Details||False positive|
|Technical Details Explanation||Security vulnerabilities found with open source libraries using Black Duck Scan:|
1. spring-tx-3.0.5.RELEASE.jar CVE-2011-2730
2. spring-web-3.0.5.RELEASE.jar CVE-2011-2730
3. spring-asm-3.0.5.RELEASE.jar CVE-2011-2730
4. spring-webmvc-3.0.5.RELEASE.jar CVE-2011-2730
Prior to JSP 2.0, Expression Language (EL) was not supported. To enable the use of EL in web applications based on earlier JSP specifications, some Spring MVC tags provide EL support independently of the Servlet/JSP container. The evaluation of EL is enabled by default. When used on containers that do support EL, the attributes can be evaluated for EL twice. Once by the container and once by the tag. This can lead to unexpected results that include disclosure of information and remote code execution (initially only information disclosure was documented but a subsequent report showed the possibility of code execution).
CVSS Base Score: 4.9
CVSS v2 Vector (AV:A/AC:M/Au:S/C:P/I:P/A:P)
Affect: In AAOP we are not using the spring MVC tags that provided the Expression Language support prior to JSP 2.0, so, AAOP is not vulnerable to this.
