CVE-2020-6844Public exploitNetwork attack vector

Account takeover chain via forged login request

Published Feb 18, 2020 · Updated Aug 4, 2024

Login CSRF in TopManage OLK Web Store 2020 allows remote attackers to facilitate account takeover through a victim's browser. The published request to /olk/client/login.asp submits credentials in an ordinary form POST, and no anti-CSRF token appears among its parameters. A victim must be induced to submit the attacker-controlled request, and account takeover requires chaining the flaw with another vulnerability.
