CVE Descriptions

FTP server in Solaris 8 and earlier allows local and remote attackers to cause a core dump in the root directory, possibly with world-readable permissions, by providing a valid username with an invalid password followed by a CWD ~ command, which could release sensitive information such as shadowed passwords, or fill the disk partition.

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.

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.

The information presented on CVE Find originates from several carefully selected reference sources. CVE data is provided by MITRE Corporation and the National Vulnerability Database (NVD). The Known Exploited Vulnerabilities (KEV) catalog is sourced from the Cybersecurity and Infrastructure Security Agency (CISA), while EPSS scores come from FIRST.org. Additionally, data regarding software weaknesses (CWE) and common attack patterns (CAPEC) is maintained by MITRE Corporation, and information on hardware and software configurations (CPE) is provided by the NVD.
