|Applies To||RSA Product Set: Adaptive Authentication (OnPrem)|
RSA Product/Service Type: Adaptive Authentication (OnPrem)
RSA Version/Condition: 7.1 P5
|Article Summary||Security vulnerability found with open source libraries using Black Duck Scan|
|Alert Impact||Not Applicable|
|Technical Details||False positive|
|Technical Details Explanation||AA-17133 Security Vulnerabilities found with open source libraries using Black Duck Scan|
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)
|Resolution||In AAoP we do not use the spring MVC tags that provided the Expression Language support prior to JSP 2.0. Therefore, AAoP is not affected by this vulnerability.|
