SB2019112817 - Multiple vulnerabilities in Octopus Deploy

Description

This security bulletin contains information about 2 secuirty vulnerabilities.

1) Cross-site request forgery (CVE-ID: CVE-2019-19375)

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.

2) Input validation error (CVE-ID: CVE-2019-19376)

The vulnerability allows a remote authenticated user to perform a denial of service (DoS) attack.

In Octopus Deploy before 2019.10.6, an authenticated user with TeamEdit permission could send a malformed Team API request that bypasses input validation and causes an application level denial of service condition. (The fix for this was also backported to LTS 2019.9.8 and LTS 2019.6.14.)

Remediation

Install update from vendor's website.
