CVE-2026-85437— MOOS-IvP through 24.8.1 Buffer Overflow in IvP Function String Decoders

Quick assessment

Affected

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

MOOS-IvP（版本 up to 24.8.1）中的 IvP 函数字符串解码器存在多个缓冲区溢出漏洞，原因是这些解码器在未进行有效校验的情况下，直接信任由攻击者控制的长度字段。攻击者可以通过构造带有不匹配的“声明长度”与“实际长度”的恶意编码字符串，从而溢出堆栈和堆缓冲区，并可能通过 MOOS 变量或 alog 文件实现远程代码执行。

Vulnerability Title
MOOS-IvP through 24.8.1 Buffer Overflow in IvP Function String Decoders
Source: CVE Program / CVE List V5
Vulnerability Description
MOOS-IvP through 24.8.1 contains multiple buffer overflow vulnerabilities in IvP function string decoders that trust attacker-controlled length fields without validation. Attackers can craft malicious encoded strings with mismatched declared and actual field lengths to overflow heap and stack buffers, potentially achieving remote code execution through MOOS variables or alog files.
