SALESmanago <= 3.2.4 - Log Injection via Weak Authentication Token

Authentication Bypass by Primary Weakness
CVE CVE-2023-4939
CVSS 5.3 (Medium)
Publicly Published October 20, 2023
Last Updated January 22, 2024
Researcher Francesco Carlucci


The SALESmanago plugin for WordPress is vulnerable to Log Injection in versions up to, and including, 3.2.4. This is due to the use of a weak authentication token for the /wp-json/salesmanago/v1/callbackApiV3 API endpoint which is simply a SHA1 hash of the site URL and client ID found in the page source of the website. This makes it possible for unauthenticated attackers to inject arbitrary content into the log files, and when combined with another vulnerability this could have significant consequences.
