Vulnerability identifier: #VU37442

CSH Severity: Medium

CVSS v4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2016-9575

CWE-ID: CWE-285

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote authenticated user to read and manipulate data.

Ipa versions 4.2.x, 4.3.x before 4.3.3 and 4.4.x before 4.4.3 did not properly check the user's permissions while modifying certificate profiles in IdM's certprofile-mod command. An authenticated, unprivileged attacker could use this flaw to modify profiles to issue certificates with arbitrary naming or key usage information and subsequently use such certificates for other attacks.
