Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Improper Authentication

EUVDB-ID: #VU24758

Risk: High

CVSSv4.0: 6.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2020-2099

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to the affected software improperly reuses encryption key parameters in the Inbound TCP Agent Protocol/3. A remote attacker with knowledge of agent names can obtain the connection secrets for those agents, which can be used to connect to Jenkins, impersonating those agents.

Mitigation

Install updates from vendor's website.

7) Clickjacking

EUVDB-ID: #VU24764

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-2105

CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a clickjacking attack

The vulnerability exists due to the affected software does not serve the "X-Frame-Options: deny" HTTP header on REST API responses to protect against clickjacking attacks. A remote attacker can rout the victim through a specially crafted web page that embeds a REST API endpoint in an iframe and trick the user to perform an action which would allow for the attacker to learn the content of that REST API endpoint.

Mitigation

Install updates from vendor's website.
