NVD description

Apache Syncope offers the ability to extend / customize the base behavior on every deployment by allowing to provide custom implementations of a few Java interfaces; such implementations can be provided either as Java or Groovy classes, with the latter being particularly attractive as the machinery is set for runtime reload. Such a feature has been available for a while, but recently it was discovered that a malicious administrator can inject Groovy code that can be executed remotely by a running Apache Syncope Core instance. Users are recommended to upgrade to version 3.0.14 / 4.0.2, which fix this issue by forcing the Groovy code to run in a sandbox.

    PoC

    ID管理基盤Apache Syncopeのリモートコード実行（RCE）脆弱性（CVE-2025-57738）に関する公開PoC（概念実証）と技術詳細が公表された。管理者権限を悪用してサーバ全体を乗っ取れる。 SecureLayer7の報告によると、Apache SyncopeにCVE-2025-57738（CVSS7.2）の脆弱性が存在する。原因はGroovyで記述された拡張コードの処理にあり、サンドボックスや制限なしでコンパイルされるため、JVM全体へのアクセスが可能となる。攻撃者は静的初期化子を悪用し、クラス読み込み時点で任意コードを実行できる。 この欠陥によりRuntime.execなどを通じたコマンド実行やファイル操作が可能となり、特にDocker環境ではroot権限で実行されるケースも確認された。実証ではidコマンド実行により完全制御が確認されている。根本原因は分離不備にあり、ユーザ提供コードの安全性検証が欠如している点が問題とされる。 https://securityonline.info/apache-syncope-rce-cve-2025-57738-poc-disclosure/

    Post summary

    Apache Syncope CVE‑2025‑57738 RCE vulnerability has been disclosed with a public PoC and detailed technical explanation, enabling full server takeover via Groovy code; no evidence of active exploitation or available patch is provided.

    Apache Syncope の RCE 脆弱性 CVE-2025-57738 が FIX：PoC の公開による悪用の可能性 https://iototsecnews.jp/2026/04/21/apache-syncope-rce-vulnerability-detailed-after-public-exploit-code-release/ Apache Syncope における脆弱性 CVE-2025-57738 は、外部から提供されたプログラムを安全に実行するための “仕切り” が不十分だったことに起因します。本来、自由にプログラムを動かせる環境では、システムを壊さないように制限をかける sandbox という仕組みが必要ですが、その制限がない状態で Groovy という強力な言語を処理していました。そのため、設定を読み込む準備段階で悪意のコードが実行され、サーバの全権限を奪われるリスクが生じています。プログラムの構造をチェックする前の段階で命令が動いてしまう仕組みや、システム側の高い権限を引き継いでしまう仕組みといった、複合的な問題が重なっています。ご利用のチームは、ご注意ください。 #Apache #CVE202557738 #PoC #Syncope #Vulnerability
