What is CVE-2025-41244?
CVE-2025-41244 is a local privilege escalation flaw in VCF operations. A local user can abuse the bug to gain higher privileges than they should hold, typically root or SYSTEM. Vendor description: VMware Aria Operations and VMware Tools contain a local privilege escalation vulnerability. A malicious local actor with non-administrative privileges having access to a VM with VMware Tools installed and managed by Aria Operations with SDMP enabled may exploit this vulnerability to escalate privileges to root on the same VM.
Why this CVE matters
Local privilege escalation flaws are a building block for the broader attack chain. They turn a low-privileged foothold, often gained through phishing or an unrelated web exploit, into full host control.
For deployments of VCF operations that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Confirmed in-the-wild exploitation makes that assumption mandatory, not cautious. Patching closes the door; log review and credential rotation close out the rest of the response.
Am I affected?
You are affected if your installation matches any of these version ranges:
- VCF operations: 9.0.x < 9.0.1.0
- VCF operations: 13.x.x.x < 13.0.5.0
- VCF operations: 12.5.x < 12.5.4
- VCF operations: 8.18.x < 8.18.5
- VCF operations: 5.x < 8.18.5
- VCF operations: 4.x < 8.18.5
- VCF operations: 5.x < 8.18.5
- VCF operations: 4.x < 8.18.5
Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.
On VMware ESXi, run vmware -vl to read the build number. On vCenter, the version is shown on the login banner and in the admin UI under the Help menu.
How to fix CVE-2025-41244
- Read the vendor advisory in full: http://support.broadcom.com/group/ecx/support-content-view/-/support-content/Security%20Advisories/VMSA-2025-0015--VMware-Aria-Operations-and-VMware-Tools-updates-address-multiple-vulnerabilities--CVE-2025-41244-CVE-2025-41245--CVE-2025-41246-/36149
- Upgrade VCF operations to the patched build listed in the vendor advisory.
- Back up the configuration (and database, where applicable) before upgrading.
- Apply the patch in a maintenance window. For HA pairs, upgrade the standby node first, fail over, then upgrade the former primary.
- Restart the affected service so the patched binary loads, then verify the new version (see verification section).
Patch via your OS package manager
# The exact package name and patched version are listed in the vendor advisory:
# https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36149
# Debian / Ubuntu
sudo apt update
sudo apt install --only-upgrade vcfoperations
# RHEL / Rocky / AlmaLinux / Fedora
sudo dnf upgrade vcfoperations
# openSUSE
sudo zypper update vcfoperations
# Verify the running version matches the fixed version
dpkg -s vcfoperations 2>/dev/null | grep -i version || rpm -q vcfoperations 2>/dev/null
# Windows: pull the cumulative update that ships this fix.
Install-Module PSWindowsUpdate -Force -SkipPublisherCheck
Get-WindowsUpdate -AcceptAll -Install -AutoReboot
Verify the fix landed
# 1. Confirm the running version matches the fixed-in version from the advisory:
# https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/36149
# Use the platform-specific version probe above.
# 2. Re-scan with your vulnerability scanner (Nessus, Qualys, Tenable, OpenVAS).
# The scanner should no longer flag CVE-2025-41244 on the patched target.
# 3. Inspect recent service / kernel logs for crash loops or rollback events.

If you cannot patch immediately
No official workaround exists beyond restricting network exposure to the affected component. Apply the vendor patch as the primary remediation.
How to verify the fix worked
- After applying the patch, verify the running version in the product's admin UI or via the vendor-documented CLI command.
- Confirm the patched build matches the version listed in the vendor advisory.
- Run an authenticated vulnerability scan with a current signature set and confirm the scanner no longer flags CVE-2025-41244.
- Review logs for the entire pre-patch window for indicators of compromise listed in the vendor or CISA advisory.
- Confirm any network-layer mitigations that were applied as a stopgap have been reverted (or left in place intentionally) once the patch is verified.
If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for log entries that do not match your normal request patterns, especially repeated requests to the same uncommon endpoint, and any administrative changes you cannot tie back to a known operator. Because VCF operations sits on CISA's Known Exploited Vulnerabilities catalog for this CVE, defenders should also pull the IOC list from the vendor advisory and from CISA's analysis if one was published.
Frequently asked questions
Is CVE-2025-41244 being exploited in the wild?
Yes. CISA added CVE-2025-41244 to the Known Exploited Vulnerabilities catalog, which means active exploitation has been confirmed by federal observation or credible vendor reporting.
Will a WAF or IDS rule fully mitigate CVE-2025-41244?
No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.
How long should I plan for the upgrade?
Typical vendor-documented upgrade windows for VCF operations run from a few minutes to under an hour depending on cluster size. Test in a staging environment first and follow the vendor's documented HA upgrade order.
