Published: 18 April 2022
Summary
CVE-2022-29457 is a high-severity Insufficiently Protected Credentials (CWE-522) vulnerability in Zohocorp Manageengine Adselfservice Plus. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 7.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Zoho ManageEngine ADSelfService Plus before version 6121, ADAuditPlus before 7060, Exchange Reporter Plus before 5701, and ADManagerPlus before 7131 contain an information disclosure flaw that exposes NTLM hashes when administrators perform certain storage-path configuration steps. The issue is tracked as CWE-522 and carries a CVSS 3.1 score of 8.8, reflecting network-accessible attack vectors that require only low privileges.
An authenticated attacker with access to the affected configuration interfaces can trigger the disclosure and obtain NTLM hashes, which may be used for pass-the-hash attacks or offline cracking to escalate privileges within the Windows domain environment. Public proof-of-concept material has been posted that demonstrates hash exposure against the vulnerable builds.
Vendor release notes indicate that upgrading ADSelfService Plus to 6121 or later, ADAuditPlus to 7060 or later, Exchange Reporter Plus to 5701 or later, and ADManagerPlus to 7131 or later resolves the exposure. The associated EPSS score has remained flat at 0.0826 with no material increase since disclosure.

Mitigating Controls
Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Training instructs users on protecting credentials from disclosure or unauthorized access.
Training records for security awareness and role-based training verify education on credential protection practices, tangibly reducing risks from mishandling or exposing credentials.
Protecting authenticator content from unauthorized disclosure and modification while requiring protective controls addresses insufficiently protected credentials.
Rules of behavior include credential protection and non-sharing requirements, reducing exposure of insufficiently protected credentials.
Terminating or revoking credentials stops use of insufficiently protected or lingering credentials post-termination.
Requiring confidentiality/integrity protection for stored credentials directly mitigates insufficiently protected credentials on disk or in configuration stores.
Credentials or keys delivered out-of-band are not exposed to interception or inadequate protection on the main transport.
