CVE-2025-34107: WinaXe 7.7 FTP Client Remote Buffer Overflow
Noroxi assessment
Priority: This week (action score 60/100)
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
- Probability of exploitation in the next 30 days: 1.3% (FIRST EPSS); higher than 70.9% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- According to the record, no fixed version is available yet.
Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
A buffer overflow vulnerability exists in the WinaXe FTP Client version 7.7 within the FTP banner parsing functionality, WCMDPA10.dll. When the client connects to a remote FTP server and receives an overly long '220 Server Ready' response, the vulnerable component responsible for parsing the banner overflows a stack buffer, leading to arbitrary code execution under the context of the user.
