Executive Summary

This vulnerability is a heap buffer over-read caused by an off-by-one error in the wolfSSH_CleanPath() function of wolfSSH. An authenticated remote attacker can exploit this by sending specially crafted SCP path input containing '/./' sequences, which triggers the function to read one byte beyond the intended buffer boundary, potentially leading to memory corruption or other security issues. [1]

Impact Analysis

The vulnerability can lead to a heap buffer over-read, which may cause memory corruption or unexpected behavior in the affected software. This could potentially be leveraged by an attacker to cause denial of service or to gain further access depending on the context, although the exact impact beyond the over-read is not detailed. [1]

Mitigation Strategies

Apply the patch that fixes the off-by-one error in the wolfSSH component. This fix was merged into the master branch of the wolfSSL project on December 30, 2025, as Pull Request #859. Updating to a version of wolfSSH that includes this patch will mitigate the vulnerability. [1]
