Title

Уязвимость подсистемы Simple Network Management Protocol (SNMP) операционной системы Cisco IOS, позволяющая нарушителю внедрить код или вызвать перезагрузку системы

Summary

Множество уязвимостей подсистемы Simple Network Management Protocol (SNMP) операционной системы Cisco IOS вызваны переполнением буфера. Эксплуатация уязвимостей может позволить нарушителю, действующему удалённо, внедрить код в систему или вызвать ее перезагрузку, используя рассылку специально созданных SNMP пакетов в систему с помощью протоколов IPv4 или IPv6. Уязвимости затрагивают все версии SNMP: 1, 2c, 3. Для эксплуатации уязвимостей подсистемы SNMP версии 2c или более ранней нарушитель должен знать строку для чтения протокола в данной системе. Для эксплуатации уязвимостей подсистемы SNMP версии 3 нарушитель должен обладать учетной записью пользователя этой системы. Все устройства, имеющие подсистему SNMP и не исключающие MIBs или OIDs, могут быть уязвимы

CVE-2017-6742 (GCVE-0-2017-6742)

Vulnerability from cvelistv5 – Published: 2017-07-17 21:00 – Updated: 2026-01-12 19:25

Summary

A vulnerability in the SNMP implementation of could allow an authenticated, remote attacker to cause a reload of the affected system or to remotely execute code. An attacker could exploit this vulnerability by sending a crafted SNMP packet to the affected device. The vulnerability is due to a buffer overflow in the affected code area. The vulnerability affects all versions of SNMP (versions 1, 2c, and 3). The attacker must know the SNMP read only community string (SNMP version 2c or earlier) or the user credentials (SNMPv3). An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system. Only traffic directed to the affected system can be used to exploit this vulnerability.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
