Description
This security bulletin contains information about 3 vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2017-12737)
CWE-ID: CWE-306 - Missing Authentication for Critical Function
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
