CVE-2022-41886 — HIGH (CVSS 7.5) AI Security Vulnerability

CISO Take

This vulnerability allows unauthenticated remote attackers to crash TensorFlow-based inference services by sending a crafted request with an oversized output shape parameter. Any externally-exposed TF image processing endpoint is a direct DoS target with no prerequisites. Patch immediately to TensorFlow 2.11, 2.10.1, 2.9.3, or 2.8.4, and add input validation at your API boundary for shape parameters.

Risk Assessment

High severity (CVSS 7.5) with low exploitability barrier: network-accessible, no authentication, no user interaction. The impact is limited to availability (no data exfiltration risk), but in production ML serving environments a persistent crash loop or repeated triggering can result in sustained service outage. Risk is elevated for computer vision APIs that accept user-controlled image transformation parameters.

PATCH

Upgrade to TensorFlow 2.11, or cherrypick commit 8faa6ea692985dbe6ce10e1a3168e0bd60a723ba into 2.10.1, 2.9.3, or 2.8.4.
VALIDATE

Add server-side bounds checking on output_shape parameters before passing to image ops — reject requests where product of dimensions exceeds a safe threshold (e.g., 4096x4096).
ISOLATE

Run TF serving workers in containers with auto-restart policies; consider per-request resource limits to contain blast radius.
MONITOR

Alert on abnormal TF worker crash rates as an indicator of exploitation attempts.
AUDIT

Inventory all internal services using ImageProjectiveTransformV2 or related projection ops.

Technical Details

NVD Description

TensorFlow is an open source platform for machine learning. When `tf.raw_ops.ImageProjectiveTransformV2` is given a large output shape, it overflows. We have patched the issue in GitHub commit 8faa6ea692985dbe6ce10e1a3168e0bd60a723ba. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.

Exploitation Scenario

An adversary identifies a public-facing image processing API backed by TensorFlow (e.g., a document digitization service, face recognition endpoint, or visual search). They send a crafted POST request with a valid image but specify an extremely large `output_shape` (e.g., [INT_MAX, INT_MAX]) in the transformation parameters. TensorFlow's buffer size calculation overflows, triggering a crash in the serving worker. The attacker repeats this in a loop at low rate to maintain continuous service degradation while evading rate-limit thresholds. In Kubernetes environments without proper liveness probe tuning, this can cause cascading restarts affecting the entire inference tier.
