CVE-2018-25315
Published: 29 April 2026
Summary
CVE-2018-25315 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Alloksoft Video (inferred from references). Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 5.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2018-25315 is a buffer overflow vulnerability affecting Alloksoft Video Joiner version 4.6.1217. The issue arises when the application processes a malicious string supplied in the License Name field during license registration, enabling attackers to overwrite the structured exception handler (SEH) and inject shellcode for arbitrary code execution. Classified under CWE-120, it carries a CVSS v3.1 base score of 8.4 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Local attackers can exploit this vulnerability without privileges, requiring low attack complexity and no user interaction. By crafting a payload targeting the License Name input, they achieve full arbitrary code execution on the affected system, potentially compromising confidentiality, integrity, and availability with high impact.
Advisories and references, including a Vulncheck advisory on the buffer overflow via License Name and an Exploit-DB entry (44364) with a proof-of-concept exploit, document the issue but provide no details on patches or vendor mitigations.
