Notifications for a CVE
Stay informed of any changes for a specific CVE.
CVE Descriptions
Unspecified vulnerability in the Client System Analyzer component in Oracle Database Server 11.1.0.7 and 11.2.0.1 and Enterprise Manager Grid Control 10.2.0.5 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the January 2011 CPU. Oracle has not commented on claims from a reliable third party coordinator that this issue involves an exposed JSP script that accepts XML uploads in conjunction with NULL bytes in an unspecified parameter that allow execution of arbitrary code.

EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

This module exploits an arbitrary file upload vulnerability on the Client
Analyzer component as included in Oracle Database 11g, which allows remote
attackers to upload and execute arbitrary code. This module has been tested
successfully on Oracle Database 11g 11.2.0.1.0 on Windows 2003 SP2, where execution
through the Windows Management Instrumentation service has been used.
