No sign of exploitation. No public exploitation artifact known so far.
A flaw in Weston Embedded uC-FTPs allows an attacker to crash the FTP server by sending a specially crafted PORT command without an IP address argument, causing the server to read memory it shouldn't access.
An out-of-bounds read vulnerability in the PORT command parameter parsing of uC-FTPs v1.98.00 allows a remote attacker to trigger a denial of service condition by omitting the IP address argument. The vulnerability is exploited via crafted FTP network packets without authentication requirements, resulting in application crash due to improper bounds checking.
In the same product, most dangerous first.
