An exploitable code execution vulnerability exists in the RDP receive functionality of FreeRDP 2.0.0-beta1+android11. A specially crafted server response can cause an out-of-bounds write resulting in an exploitable condition. An attacker can compromise the server or use a man in the middle to trigger this vulnerability.

Security readout for executives and security teams

Plain-English summary

CVE-2017-2835 is a high-severity FreeRDP client vulnerability. A malicious or compromised RDP server, or a man-in-the-middle attacker, can send a crafted response that may execute code on a user’s machine. It requires a user to connect with an affected FreeRDP build.

Executive priority

Treat this as a priority if FreeRDP is used for remote administration or access. The business risk is client compromise from a hostile RDP endpoint, but urgency depends on whether the specific affected beta build remains deployed.

Technical view

The flaw is in FreeRDP RDP receive handling in 2.0.0-beta1+android11 for Windows, OSX, and Linux. A specially crafted server response can trigger an out-of-bounds write, creating an exploitable code execution condition. CVSS v3.0 is 8.8 with network attack vector, low complexity, no privileges, and required user interaction.

Likely exposure

Exposure is limited to systems running the affected FreeRDP 2.0.0-beta1+android11 build and connecting to attacker-controlled, compromised, or intercepted RDP servers. The supplied sources do not identify other affected versions or products.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. Talos describes the issue as exploitable, and the CVE states it can be triggered by a compromised server or man-in-the-middle position.

Researcher notes

Evidence supports a client-side out-of-bounds write leading to possible code execution through crafted RDP server responses. Scope is narrow in the supplied bundle: FreeRDP 2.0.0-beta1+android11 on Windows, OSX, and Linux. No KEV listing is provided.

Mitigation direction

  • Identify and remove affected FreeRDP 2.0.0-beta1+android11 builds.
  • Check FreeRDP and Debian DSA-3923 guidance for fixed package versions.
  • Avoid connecting affected clients to untrusted RDP servers.
  • Reduce man-in-the-middle risk with trusted networks and server identity validation.
  • Prioritize replacement of beta or unsupported FreeRDP deployments.

Validation and detection

  • Inventory endpoints for FreeRDP and record exact versions.
  • Confirm whether any systems run 2.0.0-beta1+android11.
  • Review remote-access workflows using FreeRDP clients.
  • Check patch status against vendor and Debian advisory guidance.
  • Look for connections to unfamiliar or untrusted RDP servers.
