Summary
SoftEther VPN 5.02.5187 is vulnerable to Buffer Overflow in the Command.c file via the PtMakeCert and PtMakeCert2048 functions. NOTE: the Supplier disputes this because the behavior only allows a user to attack himself by typing a long string on a command line.

Summary
Memory Leak vulnerability in SoftEtherVPN 5.02.5187 allows an attacker to cause a denial of service via the UnixMemoryAlloc function. NOTE: the Supplier disputes this because the behavior is limited to a single allocation of a few hundred bytes with a command-line tool.

CVE-2025-25568 (GCVE-0-2025-25568)
Vulnerability from cvelistv5 – Published: 2025-03-12 00:00 – Updated: 2025-07-19 01:24
VLAI?
Summary
SoftEtherVPN 5.02.5187 is vulnerable to Use after Free in the Command.c file via the CheckNetworkAcceptThread function. NOTE: the Supplier disputes this because the use-after-free is not in the VPN software, but is instead in a separate tool that has no untrusted input and runs under the user's own privileges (it is a stress-testing tool for a networking stack).
