Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Privilege escalation
EUVDB-ID: #VU11820
Risk: Low
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-1079
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote authenticated attacker to gain elevated privileges on the target system.
The weakness exists in the REST interface of the pcsd service due improper sanitization of the file name from the /remote/put_file query. A remote attacker can create or overwrite arbitrary files with arbitrary data outside of the /etc/booth directory, in the context of the pcsd process and gain root privileges.
