CVE-2018-12383
5.5 · MEDIUMOverview
CVE-2018-12383 is a medium-severity vulnerability affecting redhat enterprise_linux_desktop. It was published on October 18, 2018 and has a CVSS 3.0 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Firefox < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
Remediation
Check the references section for vendor advisories and patches from redhat. Update enterprise_linux_desktop to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
