EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

The crash looks like this on Linux x64: => 0x00007f6931226f22: mov 0x8(%rcx),%eax rcx 0x303030303030300 217020518514230016 The wider context shows that the wild pointer target can be incremented with this vulnerability, which is typically enough for an exploit: => 0x00007f6931226f22: mov 0x8(%rcx),%eax <--- read 0x00007f6931226f25: test %eax,%eax 0x00007f6931226f27: je 0x7f6931226f80 0x00007f6931226f29: test $0x40000000,%eax 0x00007f6931226f2e: jne 0x7f6931226f80 0x00007f6931226f30: add $0x1,%eax <--- increment 0x00007f6931226f33: cmp $0xff,%al 0x00007f6931226f35: mov %eax,0x8(%rcx) <--- write back The base sample from which this fuzz case was generated is also attached, e3f87b25c25db8f9ec3c975f8c1211cc.swf Proof of Concept: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/37870.zip
