Scala subject to file deletion, code execution due to Java deserialization chain with LazyList object deserialization

緊急 9.8CVE-2022-36944 · GHSA-8qv5-68g4-248j · 23/09/2022 公開 · 17/06/2026 更新

要点

CVE-2022-36944 は org.scala-lang:scala-library, scala (scala-lang), scala-collection-compat (scala-lang) に影響する深刻度「緊急」 (CVSS 9.8) の脆弱性です。
今後30日間に悪用される確率（EPSS）：11.0%（全脆弱性の 95.9% より高い）。
対処：2.13.9, 2.9.0 以降に更新してください。

パッケージ	影響を受けるバージョン	修正済みバージョン
org.scala-lang:scala-library Maven	`≥ 2.13.0, < 2.13.9`	`2.13.9`
scala scala-lang	`≥ 2.13.0, < 2.13.9`	`2.13.9`
scala-collection-compat scala-lang	`< 2.9.0`	`2.9.0`

概要

Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file. On its own, it cannot be exploited. There is only a risk in conjunction with LazyList object deserialization within an application. In such situations, it allows attackers to erase contents of arbitrary files, make network connections, or possibly run arbitrary code (specifically, Function0 functions) via a gadget chain.
