CVE-2026-15496: SonicCloudOrg sonic-agent Groovy Script GroovyScriptImpl.java evalIsFailed os command injection

A vulnerability was found in SonicCloudOrg sonic-agent up to 2.7.2. The impacted element is the function evalIsFailed of the file sonic-agent/src/main/java/org/cloud/sonic/agent/tests/script/GroovyScriptImpl.java of the component Groovy Script Handler. The manipulation results in os command injection. The attack can be launched remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.

Security readout for executives and security teams

Plain-English summary

CVE-2026-15496 is an OS command injection issue in SonicCloudOrg sonic-agent’s Groovy Script Handler. Public sources say versions 2.7.0 through 2.7.2 are affected, remote exploitation is possible, and proof-of-concept exploit material is public. The affected product is reportedly no longer supported, so replacement or isolation may be more realistic than patching.

Executive priority

Prioritize this for any environment still using sonic-agent 2.7.x. The issue enables command execution, exploit material is public, and affected versions are reportedly unsupported. If present in production, treat remediation as time-sensitive even though active exploitation is not confirmed.

Technical view

The flaw affects evalIsFailed in sonic-agent/src/main/java/org/cloud/sonic/agent/tests/script/GroovyScriptImpl.java. Manipulated Groovy script handling can lead to OS command injection, mapped to CWE-77 and CWE-78. The CVSS v2 vector is 6.5 with network access, low complexity, and single authentication required. VulDB reports public exploit availability.

Likely exposure

Organizations running SonicCloudOrg sonic-agent 2.7.0, 2.7.1, or 2.7.2 are the stated exposure group. Risk is highest where sonic-agent or its script-handling features are reachable by users outside a tightly controlled admin group.

Exploitation context

Sources support public exploit availability, but not confirmed active exploitation. The CVSS vector indicates authentication is required. Because the product is described as unsupported and the vendor did not respond, defenders should not assume a vendor patch is available.

Researcher notes

Evidence is mainly from VulDB/CVE records and a public exploit repository reference. The affected component and function are named, but no vendor advisory or patch is cited. The CVSS vector shows authenticated remote attack requirements, so validation should focus on version, reachability, and script-execution permissions.

Mitigation direction

  • Inventory SonicCloudOrg sonic-agent deployments and versions immediately.
  • Remove, replace, or isolate affected unsupported versions.
  • Restrict access to sonic-agent management and Groovy script functionality.
  • Allow only trusted administrators to use script execution features.
  • Monitor host activity for unexpected child processes from sonic-agent.
  • Check project or vendor channels for any later remediation guidance.

Validation and detection

  • Confirm whether sonic-agent 2.7.0, 2.7.1, or 2.7.2 is installed.
  • Verify network exposure of sonic-agent interfaces and management paths.
  • Review who can authenticate and run Groovy script features.
  • Inspect logs for unusual Groovy script execution events.
  • Review endpoint telemetry for suspicious sonic-agent process behavior.
  • Document compensating controls if immediate replacement is not possible.
