CVE-2018-1079
pcs before version 0.9.164 and 0.10 is vulnerable to a privilege escalation via authorized user malicious REST call.
Does this matter?
Lower severity and a low EPSS score (1.08%). Track it; it rarely justifies an emergency change on its own.
Description
pcs before version 0.9.164 and 0.10 is vulnerable to a privilege escalation via authorized user malicious REST call. The REST interface of the pcsd service did not properly sanitize the file name from the /remote/put_file query. If the /etc/booth directory exists, an authenticated attacker with write permissions could create or overwrite arbitrary files with arbitrary data outside of the /etc/booth directory, in the context of the pcsd process.
