Summary
mailman vulnerabilities
Details
USN-5009-1 fixed vulnerabilities in Mailman. This update provides the corresponding updates for Ubuntu 20.04 LTS. In addition, the following CVEs were fixed:
It was discovered that Mailman allows arbitrary content injection. An attacker could use this to inject malicious content. (CVE-2020-12108, CVE-2020-15011)
It was discovered that Mailman improperly sanitize the MIME content. An attacker could obtain sensitive information by sending a special type of attachment. (CVE-2020-12137)
Original advisory details:
Andre Protas, Richard Cloke, and Andy Nuttall discovered that Mailman did not properly associate cross-site request forgery (CSRF) tokens to specific accounts. A remote attacker could use this to perform a CSRF attack to gain access to another account. (CVE-2021-42097)
Andre Protas, Richard Cloke, and Andy Nuttall discovered that Mailman’s cross-site request forgery (CSRF) tokens for the options page are derived from the admin password. A remote attacker could possibly use this to assist in performing a brute force attack against the admin password. (CVE-2021-42096)
