New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
SynopsisA web browser installed on the remote macOS host is affected by multiple vulnerabilities.
DescriptionThe version of Mozilla Firefox ESR installed on the remote macOS host is prior to 60.2.1. It is, therefore, affected by multiple vulnerabilities :
- A potentially exploitable crash in TransportSecurityInfo used for SSL can be triggered by data stored in the local cache in the user profile directory. This issue is only exploitable in combination with another vulnerability allowing an attacker to write data into the local cache or from locally installed malware. This issue also triggers a non-exploitable startup crash for users switching between the Nightly and Release versions of Firefox if the same profile is used. (CVE-2018-12385)
- 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. (CVE-2018-12383)
Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Mozilla Firefox ESR version 60.2.1 or later.
