An OS Command Injection vulnerability in Ivanti Sentry before the R10.5.2, R10.6.2 and R10.7.1 versions allows a remote unauthenticated user to achieve root-level remote code execution
Articles & Coverage 4
AnalysisAI
Remote code execution in Ivanti Sentry before R10.5.2, R10.6.2, and R10.7.1 allows unauthenticated remote attackers to achieve root-level command execution via OS command injection. With a maximum CVSS score of 10.0 and a network-accessible, no-interaction attack vector, this represents a critical exposure for any internet-facing Sentry appliance, though no public exploit has been identified at time of analysis.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against default configurations of Ivanti Sentry where the attacker has network reachability to the vulnerable service endpoint (CVSS AV:N/AC:L/PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All available signals point to this being a top-priority issue: CVSS 10.0 with AV:N/AC:L/PR:N/UI:N means trivially reachable over the network with no authentication or user interaction, and C:H/I:H/A:H with S:C means full host compromise crossing trust boundaries. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker scans for internet-exposed Ivanti Sentry administrative or system interfaces, then sends a single crafted HTTP request containing shell metacharacters in a parameter that is passed unsanitized to an OS command. The injected command executes as root on the appliance, giving the attacker a foothold from which to harvest configuration secrets (Kerberos keytabs, Exchange service credentials, certificates), pivot into the internal Exchange/AD environment, and deploy a persistent webshell or reverse tunnel. |
| Remediation | Vendor-released patches are available: upgrade to Ivanti Sentry R10.5.2, R10.6.2, or R10.7.1 (or later) on the corresponding maintenance branch per the advisory at https://hub.ivanti.com/s/article/Security-Advisory-Ivanti-Sentry-CVE-2026-10520-CVE-2026-10523?language=en_US. … Detailed patch versions, workarounds, and compensating controls in full report. |
