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.

Sense of Security - Security Advisory - SOS-13-003 security advisory Release Date. 10-Sep-2013 Last Update. - Vendor Notification Date. 27-Sep-2012 Product. Juniper Junos J-Web Platform. Junos Affected versions. All builds prior to 2013-02-28 are affected Severity Rating. Medium Impact. Privilege escalation Attack Vector. From remote with read-only authentication Solution Status. Vendor patch (not verified by SOS) Disable J-Web or limit access CVE reference. CVE - not yet assigned Details. The J-Web is a GUI based network management application used on Junos devices. The web application is vulnerable to a remote code execution vulnerability which permits privilege escalation. The file/jsdm/ajax /port.php allows execution of arbitrary user supplied PHP code via the rs POST parameter. Code executes with UID=0 (root) privileges, however you are confined to a chroot. Privilege escalation can be achieved by waiting for an administrator to log in and reading the contents of /tmp to hijack their session. Proof of Concept. Code execution: Execute a command inside the Chroot: POST /jsdm/ajax/port.php rs=exec&rsargs[]=echo “hello” Privilege escalation: Read /tmp and hijack a session POST /jsdm/ajax/port.php rs=file_get_contents&rsargs[]=/tmp Solution. All Junos OS software releases built on or after 2013-02-28 have fixed this specific issue. This fix has not been validated by SOS. As a workaround disable J-Web, or limit access to only trusted hosts. This issue is being tracked as PR 826518 and is visible on the Juniper Customer Support website. Discovered by.
