CVE-ID: CVE-2020-15396
CWE-ID:
CWE-269 - Improper Privilege Management
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
In HylaFAX+ through 7.0.2 and HylaFAX Enterprise, the faxsetup utility calls chown on files in user-owned directories. By winning a race, a local attacker could use this to escalate his privileges to root.

2) Improper Privilege Management
EUVDB-ID: #VU32880
Risk: Low
CVSSv4.0: 5.9 [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:U/U:Clear]
CVE-ID: CVE-2020-15397
CWE-ID:
CWE-269 - Improper Privilege Management
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
HylaFAX+ through 7.0.2 and HylaFAX Enterprise have scripts that execute binaries from directories writable by unprivileged users (e.g., locations under /var/spool/hylafax that are writable by the uucp account). This allows these users to execute code in the context of the user calling these binaries (often root).
MitigationUpdate the affected packages.
net-misc/hylafaxplus to version: 7.0.2
Gentoo Linux: All versions
