CVE-2026-7513
Published: 01 May 2026
Summary
CVE-2026-7513 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 37.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2026-7513 is a buffer overflow vulnerability affecting UTT HiPER 1200GW routers running versions up to 2.5.3-170306. The issue resides in the strcpy function within the /goform/formRemoteControl file, where improper input handling allows manipulation leading to a buffer overflow. This flaw, classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input), carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
The vulnerability can be exploited remotely by attackers who possess low privileges, such as authenticated users with limited access. Exploitation requires no user interaction and low attack complexity over the network, potentially allowing attackers to achieve high levels of confidentiality, integrity, and availability impacts, including arbitrary code execution or system compromise. An exploit for this vulnerability has been publicly disclosed and may be actively used by threat actors.
Advisories and additional details are available from sources including VulDB (vuldb.com/vuln/360324, vuldb.com/vuln/360324/cti, vuldb.com/submit/803996) and a GitHub repository (github.com/kirlic123/IOTvulner/blob/main/4035/4/4.md), which document the issue and exploit information. No specific patches or mitigations are detailed in the primary disclosure, emphasizing the need for practitioners to review vendor updates and restrict access to affected endpoints.
