Summary

CVE-2025-63548 is a high-severity Improper Handling of Unexpected Data Type (CWE-241) vulnerability. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 35.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2025-63548 is a denial-of-service vulnerability affecting Eprosima Micro-XRCE-DDS Agent version 3.0.1. The issue arises when the agent processes a specially crafted packet containing a non-valid value in any Boolean field, leading to a crash or service disruption. It has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and is associated with CWE-241.

A remote attacker can exploit this vulnerability without authentication or user interaction by sending a malicious packet over the network. Successful exploitation results in high-impact availability disruption, such as denial of service against the affected agent, with low attack complexity required.

Mitigation details and further discussion are available in the referenced advisories, including the GitHub issue at https://github.com/eProsima/Micro-XRCE-DDS-Agent/issues/389 and a CVE listing at https://github.com/j4kb4dw0lf/CVEs/blob/main/README.md.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly mitigates the vulnerability by requiring validation of Boolean fields in incoming XRCE-DDS packets to reject non-valid values before processing.

SI-11 Error Handling good match
prevent

Ensures the agent handles errors from invalid Boolean values in crafted packets without crashing or disrupting service availability.

SC-5 Denial-of-service Protection good match
prevent

Protects against denial-of-service from remote malformed packet attacks by limiting effects and rejecting prohibitive communications.
