CVE-2025-31175

CVE-2025-31175: DSoftBus Deserialization Mismatch Vulnerability

Description: A deserialization mismatch vulnerability exists within the DSoftBus module. This vulnerability arises from inconsistencies in how data is serialized and deserialized.

Severity: High

  • CVSS Score: 8.4 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
  • Vector String: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Impact: Successful exploitation of this vulnerability could compromise service integrity by potentially allowing an attacker to manipulate data or control application flow through crafted serialized objects.

Known Exploit: Currently, there is no publicly available exploit. However, the CVSS score indicates potential for remote exploitation without user interaction.

Remediation/Mitigation Strategy:

  1. Apply Security Patches: Immediately apply any security patches released by Huawei to address CVE-2025-31175. This is the primary and most effective mitigation. Monitor Huawei’s security advisories for updates and instructions.

  2. Input Validation: Implement strict input validation on all data received by the DSoftBus module, especially data that is to be deserialized. Specifically:

    • Type Checking: Verify that the types of deserialized objects match expected types.
    • Range Checking: Validate the ranges and values of deserialized data fields.
    • Whitelisting: Where possible, use a whitelist approach to only allow deserialization of known and trusted object types.

  3. Object Stream Filtering: If possible, filter incoming object streams to remove or sanitize potentially malicious objects before deserialization occurs.

  4. Monitor for Anomalous Activity: Implement robust monitoring and logging to detect any unusual behavior related to the DSoftBus module, such as:

    • Unexpected deserialization errors
    • Data corruption
    • Service disruptions

  5. Disable Unnecessary Features: If possible, disable any DSoftBus features that are not essential to the system’s operation. This reduces the attack surface.

  6. Principle of Least Privilege: Ensure that the DSoftBus module, and any processes that interact with it, are running with the least privileges necessary. This limits the potential impact of a successful exploit.

  7. Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities. This should include specific focus on deserialization vulnerabilities.

  8. Code Review: Perform thorough code reviews of the DSoftBus module’s serialization and deserialization logic to identify and correct any potential flaws.

  9. Network Segmentation: Isolate the DSoftBus module within a segmented network to limit the potential spread of an attack.

Timeline for Remediation:

  • Immediate (within 24 hours): Patch deployment (if available), initial review of logs and monitoring.
  • Within 1 week: Implement input validation measures.
  • Within 1 month: Conduct a thorough security audit and penetration test. Complete code review.
