Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Privilege escalation
EUVDB-ID: #VU12975
Risk: Low
CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2018-1122
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to top reads its configuration file from the current working directory, without any security check, if the HOME environment variable is unset or empty. A local attacker can exploit one of several vulnerabilities in top's config_file() function, execute top in /tmp (for example) and gain elevated privileges.
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
