Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache Camel Crypto PGP 组件中存在“完整性校验值验证不当”的漏洞。 该问题影响 Apache Camel 的以下版本：4.0.0 至 4.18.5 之前的版本，以及 4.19.0 至 4.22.1 之前的版本。 在 unmarshal() 方法中，仅当消息为 OpenPGP 对称加密且带有完整性保护的数据包时，才会验证修改检测码（Modification Detection Code, MDC）。而较旧的对称加密数据包并不包含此类代码；由于 OpenPGP 的 CFB 模式在没有 MDC 的

Vulnerability Title
Apache Camel: Camel-Crypto-PGP Integrity Verification Downgrade via Attacker-Controlled Message Structure
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Validation of Integrity Check Value vulnerability in Apache Camel Crypto PGP component.
This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1.
unmarshal() verified the modification detection code only when the message was an OpenPGP symmetrically encrypted integrity protected data packet. The older symmetrically encrypted data packet carries no such code, and OpenPGP's CFB mode is malleable without one, so a message using that packet skipped the check altogether. The packet type is chosen by whoever produced the message, which left the sender - or anyone able to rewrite the message in transit - deciding whether the integrity check applied at all. The existing integrity option governs marshalling only and had no decrypt-side counterpart, so a deployment could not require integrity protection on the messages it accepted.
Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. A requireIntegrityProtection option, defaulting to true, now rejects a message that is not integrity protected. Note that signatureVerificationOption still defaults to optional, so a message carrying no signature is accepted; the two options together are what give a decrypted message authenticity and not only confidentiality. For deployments that cannot upgrade immediately, reject messages that do not use the integrity protected packet before they reach the data format. Routes that must interoperate with a sender still emitting the legacy packet should set requireIntegrityProtection=false after upgrading, and treat the decrypted content as unauthenticated.
