Name of the Vulnerable Software and Affected Versions TEKNOTEL CBW700N version 81.447.392110.729.024

Description The issue allows remote attackers to discover credentials via specific SNMP requests, including "iso.3.6.1.4.1.4491.2.4.1.1.6.1.1.0" and "iso.3.6.1.4.1.4491.2.4.1.1.6.1.2.0".

Recommendations For version 81.447.392110.729.024, consider restricting access to the SNMP service to minimize the risk of exploitation. As a temporary workaround, limit the use of the affected iso.3.6.1.4.1.4491.2.4.1.1.6.1.1.0 and iso.3.6.1.4.1.4491.2.4.1.1.6.1.2.0 SNMP requests until a patch is available.
