CVE-2025-14847
嗯，用户让我帮忙总结一篇文章，控制在100字以内，而且不需要特定的开头。首先，我得仔细阅读文章内容，抓住关键点。 文章讲的是CVE-2025-14847，也就是MongoBleed漏洞。这是一个未认证的信息泄露漏洞，影响MongoDB服务器处理zlib压缩网络消息的方式。攻击者发送特制数据包，导致服务器返回未初始化的堆内存给客户端。因为这个漏洞在认证前就能被利用，所以暴露在互联网上的MongoDB服务器风险很高。 然后，漏洞已经被积极利用，并被CISA列为已知被利用的漏洞。技术细节方面，问题出在处理长度字段时出错，导致读取未初始化的内存。影响包括泄露敏感数据如凭证、API密钥等。严重性评分是CVSS v4.0 8.7和v3.1 7.5。 修复建议包括升级到特定版本或禁用zlib压缩。此外，文章还提到了检测指标和受影响版本。 现在需要把这些信息浓缩到100字以内。要涵盖漏洞名称、类型、影响、攻击方式、风险、修复措施以及严重性评分。 可能的结构：MongoBleed（CVE-2025-14847）是一个未认证的信息泄露漏洞，影响MongoDB服务器处理zlib压缩消息。攻击者发送特制包获取未初始化内存，导致敏感数据泄露。该漏洞已遭利用，风险高。修复方法包括升级版本或禁用zlib压缩。 </think> MongoBleed（CVE-2025-14847）是一种未认证的信息泄露漏洞，影响MongoDB服务器处理zlib压缩网络消息的方式。攻击者通过发送特制数据包可获取服务器未初始化堆内存中的敏感数据（如凭证、API密钥等），风险较高且已被活跃利用。修复方法包括升级到指定版本或禁用zlib压缩功能。 2026-1-6 17:31:0 Author: horizon3.ai(查看原文) 阅读量:9 收藏

CVE-2025-14847 (MongoBleed) is an unauthenticated information disclosure vulnerability in MongoDB Server’s handling of zlib-compressed network messages. By sending specially crafted packets, an attacker can trigger MongoDB to return uninitialized heap memory to the client. Because the vulnerable path is reachable prior to authentication, internet-exposed MongoDB servers are at elevated risk.

This vulnerability is being actively exploited and has been added to CISA’s Known Exploited Vulnerabilities catalog. CISA lists a Date Added of December 29, 2025, with a federal remediation due date of January 19, 2026.

Technical details

  • Vulnerability class: Read of uninitialized heap memory caused by incorrect handling of length fields in zlib-compressed MongoDB wire protocol messages.
  • Exploitation mechanics: The affected code path can return the allocated output buffer length instead of the actual decompressed data length. This results in disclosure of adjacent heap memory to an unauthenticated client. The issue resides in MongoDB’s zlib message decompression logic.
  • Impact: Leaked memory fragments may contain sensitive in-memory data such as credentials, API keys, session tokens, internal state, logs, or other secrets present in the MongoDB process at the time of exploitation.

Severity (as published by MongoDB, Inc., the CNA for this CVE):

  • CVSS v4.0 base score: 8.7 (High).
  • CVSS v3.1 base score: 7.5 (High).

NodeZero® Offensive Security Platform — Rapid Response

If CVE-2025-14847 Rapid Response coverage is available in your customer portal, use it to validate whether MongoDB servers are exploitable, then re-run testing after remediation to confirm exposure has been removed.

  • Run the Rapid Response test: Validate whether targeted MongoDB servers are vulnerable to CVE-2025-14847, prioritising internet-exposed deployments where zlib compression is enabled.
  • Patch immediately: Upgrade to a fixed MongoDB version (8.2.3, 8.0.17, 7.0.28, 6.0.27, 5.0.32, or 4.4.30).
  • If you cannot patch immediately: Disable zlib compression by configuring networkMessageCompressors or net.compression.compressors to omit zlib (for example, snappy,zstd or disabled).
  • Re-run the Rapid Response test: Confirm that remediation removed exploitability.

If a MongoDB server was internet exposed and vulnerable, treat this as a potential secrets exposure event. Assume credentials and tokens that may have been present in memory could be compromised and respond accordingly.

Indicators of compromise (hunting guidance)

This is a memory disclosure vulnerability, so file hashes and dropped artifacts are not primary indicators. Focus on behavioural and traffic-based signals:

  • Abnormal spikes in inbound connections to MongoDB, especially large numbers of short-lived, pre-authentication connections from the same source.
  • Repeated probing patterns against MongoDB services consistent with attempts to elicit leaked memory contents.
  • Suspicious use of compressed MongoDB traffic if protocol-aware network telemetry is available.
  • Reports of instability or crashes coinciding with unusual inbound traffic patterns.

Affected versions and patch

Affected MongoDB versions:

  • MongoDB 8.2.0 through 8.2.2
  • MongoDB 8.0.0 through 8.0.16
  • MongoDB 7.0.0 through 7.0.26
  • MongoDB 6.0.0 through 6.0.26
  • MongoDB 5.0.0 through 5.0.31
  • MongoDB 4.4.0 through 4.4.29
  • All MongoDB Server v4.2 versions
  • All MongoDB Server v4.0 versions
  • All MongoDB Server v3.6 versions

Remediation:

  • Upgrade to one of the following fixed versions: 8.2.3, 8.0.17, 7.0.28, 6.0.27, 5.0.32, or 4.4.30.

Workaround (if patching is not immediately possible):

  • Disable zlib compression by explicitly omitting zlib from networkMessageCompressors or net.compression.compressors.
