Weston Embedded uC-HTTP is a popular HTTP server used in embedded devices. Researchers have discovered a heap-based buffer overflow vulnerability in its network handling code.

A buffer overflow occurs when a program tries to store more data in a buffer (block of memory) than it was intended to hold. This can corrupt memory and allow attackers to execute arbitrary code.

In this case, by sending a specially crafted set of network packets, a remote attacker could potentially take control of devices running vulnerable versions of uC-HTTP. They would then be able to do things like access files, change settings, or even install new programs without authorization.

The vulnerability has been given a CVSS score of 9 out of 10, meaning it is relatively easy to exploit and can result in complete system compromise if not patched. Devices using uC-HTTP versions 3.01.01 and earlier are affected.

If you use uC-HTTP in your embedded projects, it is highly recommended to update to the latest version immediately. Also consider changing default credentials if applicable. Staying on top of software updates is one of the best ways to bolster the security of internet-connected devices.
