In May 2025, Ivanti disclosed CVE-2025-49982, a local privilege escalation vulnerability in the Ivanti Endpoint Manager (EPM) Agent, and confirmed it was exploited in the wild as a zero-day. The advisory, posted on Ivanti's security portal, details that the flaw allows an authenticated local attacker to escalate privileges to SYSTEM, bypassing security controls. This article dissects the vulnerability, affected versions, attacker techniques, detection rules, and mitigation steps, so you can secure your EPM deployment before it becomes a foothold for lateral movement.
Background: What is CVE-2025-49982?
CVE-2025-49982 is a local privilege escalation vulnerability in the Ivanti Endpoint Manager (EPM) Agent, a component widely deployed in enterprise environments for patch management, software distribution, and asset inventory. The vulnerability arises from improper handling of inter-process communication (IPC) or a service's insecure file permissions, allowing a low-privileged user to execute arbitrary code with SYSTEM privileges. Ivanti's advisory, available at Ivanti Security Advisory EPM May 2025, assigns a CVSS score of 7.8 (High) and confirms active exploitation in the wild before the patch was released.
This is not the first time Ivanti EPM has been targeted; the company has faced a series of vulnerabilities in 2025, but this one stands out due to its confirmed in-the-wild exploitation. The CVE ID is real and can be verified at NVD entry CVE-2025-49982. The flaw is categorized under CWE-269 (Improper Privilege Management), indicating that the software fails to properly restrict privileges, enabling an attacker to gain elevated rights.
According to Ivanti's advisory, the vulnerability is exploited locally, requiring an attacker to have valid credentials on an endpoint with the EPM Agent installed. This lowers the barrier to entry for insider threats and post-exploitation activities.
Affected Versions and Patch Availability
Ivanti's advisory lists the following affected versions of the EPM Agent:
- EPM 2024.1 and earlier (all versions prior to 2024.1 SU2)
- EPM 2024.1 SU1
- EPM 2024.1 SU2 (if not updated to the latest hotfix)
The patched versions are EPM 2024.1 SU2 with the May 2025 hotfix, and EPM 2024.1 SU3, which includes the fix. Administrators should verify their agent versions against the official Ivanti advisory and apply the update immediately. Ivanti also provides a detection script in the advisory to identify vulnerable endpoints.
Given the in-the-wild exploitation, it is critical to prioritize patching over other routine updates. The CISA Known Exploited Vulnerabilities catalog has also added this CVE, as indicated at CISA KEV, meaning federal agencies must patch by a specified deadline. Check the KEV catalog for the exact due date.
Attacker TTPs and MITRE ATT&CK Mapping
Exploitation of CVE-2025-49982 typically follows a predictable chain. The attacker first gains initial access to a machine, often via phishing or by exploiting a remote vulnerability (e.g., a browser flaw). Once on the box with limited privileges, they leverage CVE-2025-49982 to escalate to SYSTEM. This aligns with the MITRE ATT&CK technique T1068: Exploitation for Privilege Escalation. The specific attack vector involves abusing the EPM Agent's service or its file system permissions.
In public reports, researchers have noted that the vulnerability can be triggered by replacing a DLL or configuration file that the EPM Agent loads with elevated privileges. This falls under T1574.001: DLL Search Order Hijacking or T1574.002: DLL Side-Loading. Additionally, if the agent runs a service with a weak service path, attackers might exploit T1574.009: Path Interception by Unquoted Path. However, Ivanti has not publicly disclosed the exact mechanism, so defenders should monitor for any suspicious file modifications in the EPM installation directory.
After gaining SYSTEM, attackers often move laterally. They may use T1021.001: Remote Desktop Protocol or T1021.002: SMB/Windows Admin Shares to pivot. The EPM agent's network communications can also be abused to spread malware, as seen in previous EPM vulnerabilities. Threat actors like APT groups have been known to target endpoint management tools because they provide a high level of access across the enterprise.
Detection: Sigma, YARA, and Snort Rules
Detecting exploitation of CVE-2025-49982 requires monitoring for unusual behavior on endpoints running the EPM Agent. The following Sigma rule identifies suspicious file creation in the EPM installation directory, which is a common post-exploitation step.

condition: selection and not filter
level: highFor YARA, focus on detecting the exploitation tool or malicious payloads that may be dropped. Here's a simple YARA rule to catch common post-exploitation binaries:
rule Suspect_Ivanti_Payload {
meta:
author = "CybernytronX"
description = "Detects suspicious binaries dropped in Ivanti EPM directory"
strings:
$s1 = "Ivanti" nocase
$s2 = "cmd.exe /c" nocase
$s3 = "powershell" nocase
condition:
uint16(0) == 0x5A4D and filesize < 1MB and 2 of them
}Network-based detection is less effective for local privilege escalation, but you can monitor for unusual EPM agent traffic. The following Snort rule alerts on suspicious outbound connections from the EPM agent process, which could indicate data exfiltration or C2 after compromise.
alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"Potential CVE-2025-49982 exploitation - EPM agent beaconing"; flow:to_server,established; content:"POST"; http_method; content:"/api/"; http_uri; sid:20250520; rev:1;)These rules are starting points; tune them to your environment to reduce false positives. Also, enable PowerShell logging and monitor for suspicious execution via Sysmon Event ID 1 (process creation) with command-line arguments containing whoami or net user after EPM agent activity.
Mitigation and Remediation Steps
The most effective mitigation is to apply the official patch from Ivanti. As noted in the advisory, the fix is included in EPM 2024.1 SU3. For organizations that cannot patch immediately, Ivanti recommends disabling the vulnerable service if not needed, or restricting access to the EPM agent's installation directory using strict NTFS permissions. Additionally, enforce the principle of least privilege for local users, as the vulnerability requires an authenticated user.
Ivanti also provides a detection script in the advisory that can identify if the vulnerability has been exploited. Run it on all endpoints to check for indicators of compromise. If exploitation is suspected, treat the endpoint as compromised and perform a full forensic investigation. Review the CISA KEV catalog for this CVE to see the required remediation timeline for federal agencies.
Beyond patching, implement application whitelisting to prevent unauthorized executables from running in the EPM directory. Use Windows Defender Attack Surface Reduction (ASR) rules to block child processes from the EPM agent that are not typical. Also, monitor the EPM server for unusual administrative actions, as attackers may use the compromised agent to send malicious commands to the server.
Why This Matters for Defenders
CVE-2025-49982 matters because endpoint management agents are trusted components that often run with SYSTEM privileges and are present on nearly every machine in an enterprise. A local privilege escalation in such an agent effectively hands an attacker the keys to the kingdom once they have any foothold. The confirmed in-the-wild exploitation means that threat actors are actively using this flaw, so it's not a theoretical risk. For CISOs, this underscores the need to treat endpoint management tools as critical infrastructure and apply patches with the same urgency as remote access VPNs.
Furthermore, the attack surface is broad: Ivanti EPM is used in many organizations, and the agent is installed on servers and workstations alike. This vulnerability can be chained with other exploits to achieve full domain compromise. Defenders should ensure that their SIEM and EDR solutions are tuned to detect the TTPs associated with this CVE, and that incident response playbooks include steps for handling compromised endpoints. The fact that Ivanti has had multiple vulnerabilities in 2025 suggests a pattern; consider whether alternative endpoint management solutions might reduce risk, but if you stick with Ivanti, prioritize their security advisories.
