The web interface on multiple Omada switches does not adequately validate certain external inputs, which may lead to out-of-bound memory access when processing crafted requests. Under specific conditions, this flaw may result in unintended command execution.An unauthenticated attacker with network access to the affected interface may cause memory corruption, service instability, or information disclosure. Successful exploitation may allow remote code execution or denial-of-service.

Improper Restriction of Operations within the Bounds of a Memory Buffer 🎯 High

The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

🛡️ Empfohlene Mitigation: Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow prot…
