Be the first to know when new zero-days emerge:

Summary

CVE-2026-6516 is a critical unauthenticated remote code execution (RCE) vulnerability in Zohocorp ManageEngine ADAudit Plus, affecting all builds prior to 8606. The flaw resides in the product’s agent API, where an authentication bypass and a path traversal weakness can be chained by a remote, unauthenticated attacker to execute arbitrary code on the server. It carries a CVSS v3.1 base score of 10.0 — the maximum possible severity rating.

Technical details

  • Root cause: Two distinct weaknesses in the ADAudit Plus agent API: an authentication bypass flaw and a path traversal vulnerability.
  • Trigger conditions: An unauthenticated attacker reachable over the network can combine the authentication bypass and path traversal to interact with agent API endpoints without any credentials or user interaction.
  • Attack vector: Network-accessible; no privileges or user interaction required (AV:N/AC:L/PR:N/UI:N). The ADAudit Plus web interface and agent API are routinely exposed on enterprise networks.
  • Impact: Successful exploitation results in remote code execution on the ADAudit Plus server. Given the product’s privileged role in Active Directory environments — continuously collecting and auditing domain controller events — a compromise can lead to Active Directory takeover and mass credential and event-log data exfiltration.

Affected software

  • Zohocorp ManageEngine ADAudit Plus — all builds prior to build 8606

Severity

  • CVSS v3.1 Base Score: 10.0 (Critical)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:L

Mitigation and recommended actions

  • Immediate: Update ManageEngine ADAudit Plus to build 8606 or later using the vendor-provided service pack.
  • Agent updates required after patching: Windows agents running versions earlier than 7060 must also be upgraded (verify via Configuration → Agent Management → Manage → Installed Version).

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
