CVE-2018-25283
Published: 26 April 2026
Summary
CVE-2018-25283 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Securimport (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-2018-25283 is a structured exception handling (SEH) buffer overflow vulnerability in iSmartViewPro version 1.5. The issue affects the 'Save Path for Snapshot and Record file' field accessible through the System Setup interface, where insufficient bounds checking allows overflow when processing inputs exceeding 260 bytes. This flaw, classified under CWE-120 (Buffer Copy without Checking Size of Input), enables attackers to overwrite SEH records, as indicated by its 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 by supplying a crafted payload via the affected field. Successful exploitation overwrites SEH records, allowing execution of arbitrary shellcode with the privileges of the iSmartViewPro application, potentially leading to full compromise of the system running the software.

Directly mandates timely identification, reporting, and correction of the buffer overflow flaw in iSmartViewPro, eliminating the vulnerability through patching or replacement.
Requires validation of inputs to the 'Save Path for Snapshot and Record file' field to enforce bounds checking and prevent oversized payloads from causing SEH buffer overflows.
Implements memory safeguards such as DEP, ASLR, and stack canaries to block arbitrary code execution even if the SEH buffer overflow occurs.
