MOOS core-moos through 10.4.0 contains a buffer overflow vulnerability in CMOOSSerialPort::GetTelegram() that writes a NUL terminator one byte past the serial telegram stack buffer. Attackers controlling the serial line can send a full-length telegram to trigger the off-by-one write, corrupting the stack and potentially enabling code execution.
AnalysisAI
Stack corruption with potential code execution in MOOS core-moos through version 10.4.0 arises from an off-by-one error in CMOOSSerialPort::GetTelegram(), where a NUL terminator is written one byte past the end of a fixed-size stack buffer. An attacker who controls the serial communication line connected to a MOOS-enabled platform can send a full-length telegram to trigger the overwrite, corrupting adjacent stack memory and potentially redirecting execution. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires physical control of the serial communication line directly connected to the MOOS-enabled system. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H assigns a Physical attack vector, which is the dominant risk-limiting factor - exploitation requires direct control of the serial communication line interfacing with the target hardware, restricting the attacker population to physically proximate actors, insiders, or supply-chain adversaries. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the upstream fix from GitHub PR #73 (https://github.com/themoos/core-moos/pull/73) or incorporate commit befb04df2039d0080715ea35f56268092db4ec0f directly into local builds. … Detailed patch versions, workarounds, and compensating controls in full report. |
