The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued an alert regarding a critical authentication bypass vulnerability, registered as “CVE-2021-4053,” that affects Zoho’s “ManageEngine ADSelfService Plus.” The vulnerability affects ManageEngine, a self-service password management and single sign-on solution from the online productivity vendor. The vulnerability is a Remote Code Execution (RCE) bypass vulnerability that could allow for remote code execution if exploited, according to the CISA. A successful exploitation of the vulnerability allows an actor to place webshells, which enable the adversary to conduct post-exploitation activities, such as compromising administrator credentials, lateral movement, and exfiltrating registry hives and Active Directory files. Zoho released a patch for this vulnerability on September 6, but CISA claimed that malicious actors might have been exploiting it as far back as August.Analyst Comment: Users should immediately apply the patch released by Zoho. Continuing usage of vulnerable applications will increase the likelihood that threat actors will attempt to exploit them, especially with open sources discussing the details of some vulnerabilities. These sources could allow some actors to create exploits to vulnerable software w ..
