Vulnerability in tensorflow (CVE-2022-35997)
Summary
Vulnerability in tensorflow (CVE-2022-35997). Risk of unauthorized operations or information disclosure. Exploitable via tf.sparse.cross. Mitigation: upgrade to 2.9.1 or later.
Original description
The description as published by the source.
Impact
If tf.sparse.cross receives an input separator that is not a scalar, it gives a CHECK fail that can be used to trigger a denial of service attack.
import tensorflow as tf
tf.sparse.cross(inputs=[],name='a',separator=tf.constant(['a', 'b'],dtype=tf.string))
Patches
We have patched the issue in GitHub commit 83dcb4dbfa094e33db084e97c4d0531a559e0ebf.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.

CVE-2022-35997 (tensorflow) — CWE-617
Attack vector: remote (network-reachable) / unauthenticated / no user interaction
Attack surface: tf.sparse.cross / separator / CHECK
Patched: 2.9.1 — apply immediately
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
A vulnerability (CWE-617) exists in tensorflow. Attackers reach the vulnerable code path via tf.sparse.cross without authentication.
Check the vendor advisory for the affected versions of tensorflow. Attack surface: tf.sparse.cross / separator / CHECK.
Severity: ?. Risk of unauthorized operations or information disclosure.
Update to 2.9.1.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'tensorflow' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response actions

-
1Identify exposure identify
grep -r 'tensorflow' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
tensorflowを grep し、稼働しているサービス・バージョンを把握する。 -
2Apply patch patch
Upgrade tensorflow to 2.9.1ステージング環境で 2.9.1 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。
-
3Post-deployment verification verify
Confirm patched version is live in productionパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
