CVE-2024-35276

CVE-2024-35276 is a stack-based buffer overflow vulnerability (CWE-121, CWE-787) affecting multiple Fortinet products, including FortiAnalyzer versions 7.4.0 through 7.4.3, 7.2.0 through 7.2.5, 7.0.0 through 7.0.12, and 6.4.0 through 6.4.14; FortiManager versions 7.4.0 through 7.4.3, 7.2.0 through 7.2.5, 7.0.0 through 7.0.12, and 6.4.0 through 6.4.14; FortiManager Cloud versions 7.4.1 through 7.4.3, 7.2.1 through 7.2.5, 7.0.1 through 7.0.11, and 6.4.1 through 6.4.7; and FortiAnalyzer Cloud versions 7.4.1 through 7.4.3, 7.2.1 through 7.2.5, 7.0.1 through 7.0.11, and 6.4.1 through 6.4.7. The vulnerability, published on January 14, 2025, has a CVSS v3.1 base score of 5.6 (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L).

A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted packets to the affected devices, potentially leading to execution of unauthorized code or commands. The high attack complexity (AC:H) limits feasibility, but successful exploitation could result in low-level impacts: limited confidentiality, integrity, and availability effects without scope change.
