Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Cleartext storage of sensitive information
EUVDB-ID: #VU25574
Risk: Medium
CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-5400
CWE-ID:
CWE-312 - Cleartext Storage of Sensitive Information
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the affected software logs app environment variables when an app is deployed using a server-side manifest, which may include sensitive information such as credentials if provided to the job. A remote authenticated attacker with access to those logs may gain unauthorized access to resources protected by such credentials.
MitigationInstall updates from vendor's website.
Vulnerable software versionsCF Deployment: 12.0.0 - 12.32.0
Cloud Controller: before 1.91.0
