CVE-2022-2191

Vulnerability in org.eclipse.jetty:jetty-server (CVE-2022-2191)

Summary

Vulnerability in org.eclipse.jetty:jetty-server (CVE-2022-2191). Risk of unauthorized operations or information disclosure. Exploitable via SslConnection. Mitigation: upgrade to 11.0.10 or later.

Original description

The description as published by the source.

Impact

SslConnection does not release ByteBuffers in case of error code paths.
For example, TLS handshakes that require client-auth with clients that send expired certificates will trigger a TLS handshake errors and the ByteBuffers used to process the TLS handshake will be leaked.

Workarounds

Configure explicitly a RetainableByteBufferPool with max[Heap|Direct]Memory to limit the amount of memory that is leaked.
Eventually the pool will be full of "active" entries (the leaked ones) and will provide ByteBuffers that will be GCed normally.

With embedded-jetty

int maxBucketSize = 1000;
long maxHeapMemory = 128 * 1024L * 1024L; // 128 MB
long maxDirectMemory = 128 * 1024L * 1024L; // 128 MB
RetainableByteBufferPool rbbp = new ArrayRetainableByteBufferPool(0, -1, -1, maxBucketSize, maxHeapMemory, maxDirectMemory);

server.addBean(rbbp); // make sure the ArrayRetainableByteBufferPool is added before the server is started
server.start();

With jetty-home/jetty-base

Create a ${jetty.base}/etc/retainable-byte-buffer-config.xml

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "https://www.eclipse.org/jetty/configure_10_0.dtd">

And then reference it in ${jetty.base}/start.d/retainable-byte-buffer-config.ini

etc/retainable-byte-buffer-config.xml

🔧 How to fix

Update to 11.0.10.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Audit SBOM/dependencies to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

1
Identify exposure identify
```
Audit SBOM/dependencies for affected components.
```
資産台帳・SBOM・依存マニフェストで org.eclipse.jetty:jetty-server を使っているサービスとバージョンを洗い出す。
2
Apply patch patch
```
Upgrade org.eclipse.jetty:jetty-server to 11.0.10
```
ステージング環境で 11.0.10 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。
3
Post-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。
