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.

A trigger is attached, signal_sigsegv_7ffff5b5aee2_252_0688bbd450e7c095265d00be2fca50ab.swf The base file from which this fuzz case was generated is attached, 0688bbd450e7c095265d00be2fca50ab.swf The crash on 64-bit Linux looks like this: => 0x00007f69314b8f7d: cmpl $0xc,0x174(%rax) rax 0x83071500ff0300 36881008741516032 If we trace through the usages of %rax, we can get to some bad writes pretty easily: => 0x00007f69314b8f7d: cmpl $0xc,0x174(%rax) 0x00007f69314b8f84: je 0x7f69314b8fa0 ... 0x00007f69314b8fa0: mov (%rax),%rdi <-- rdi compromised 0x00007f69314b8fa3: callq 0x7f69314b8810 ... 0x00007f69314b8810: mov (%rsi),%edx 0x00007f69314b8812: cmp $0x7ffffff,%edx 0x00007f69314b8818: je 0x7f69314b8862 0x00007f69314b881a: mov 0x10(%rdi),%eax 0x00007f69314b881d: cmp $0x7ffffff,%eax 0x00007f69314b8822: je 0x7f69314b8868 0x00007f69314b8824: sub $0x1,%edx 0x00007f69314b8827: cmp %eax,%edx 0x00007f69314b8829: cmovg %eax,%edx 0x00007f69314b882c: mov 0x14(%rdi),%eax 0x00007f69314b882f: mov %edx,0x10(%rdi) <---- rdi written to Proof of Concept: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/37866.zip
