Detailsinfo

A vulnerability, which was classified as critical, has been found in Eclipse NetX Duo up to 6.5.1.202602. Affected by this issue is the function _nx_snmp_utility_object_id_get of the component SNMP Addon. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

hey, `_nx_snmp_utility_object_id_get` in the NetX Duo SNMP addon does not validate the claimed OID data length against the actual buffer size when the OID uses BER multibyte length encoding, so a remote attacker can send a crafted SNMP packet with a multibyte OID length larger than the available buffer, causing the parser to read past the packet buffer boundary into adjacent heap memory. the OOB bytes are decoded as OID component values and written into the agents internal OID string buffer, corrupting agent state. on systems with memory protection the OOB read poses the risk of crashing the SNMP agent thread, causing denial of service. on bare metal embedded systems without memory protection the read silently succeeds and corrupts the agents internal state with heap data.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-102718 since 09/29/2026. The exploitation is known to be easy. The attack may be launched remotely. There are known technical details, but no exploit is available.
