Published: 26 April 2026
Summary
CVE-2018-25263 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Faleemi Desktop Software (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 4.3th 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-2018-25263 is a local buffer overflow vulnerability (CWE-120) affecting Faleemi Desktop Software version 1.8.2, specifically in the Device alias field within the Managing Log interface. The flaw enables a structured exception handler (SEH) overwrite when a malicious payload is pasted into the field, as documented in the CVE description published on 2026-04-26. 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), reflecting high impact on confidentiality, integrity, and availability.
Local attackers with access to the affected system can exploit this vulnerability by crafting a malicious payload and pasting it into the Device alias field, triggering the SEH overwrite to achieve arbitrary code execution. A proof-of-concept demonstrates successful execution of the calculator application, confirming remote code execution potential under local attack conditions with low complexity and no required privileges.
