CVE-2023-20198
Em resumo
Uma falha crítica na interface web do Cisco IOS XE permite que invasores acessem o dispositivo sem autenticação e executem comandos com altos privilégios. Essa brecha está sendo explorada ativamente para criar contas de usuário maliciosas e instalar backdoors persistentes em equipamentos de rede.
Detalhe técnico
CVE-2023-20198 é uma vulnerabilidade de execução remota de código não autenticada na interface web do Cisco IOS XE que permite aos atacantes executar comandos de nível de privilégio 15 sem autenticação prévia. A vulnerabilidade é explorada em conjunto com CVE-2023-20273 para alcançar escalonamento de privilégio até root e instalação de implantes persistentes em dispositivos afetados.

Cisco is providing an update for the ongoing investigation into observed exploitation of the web UI feature in Cisco IOS XE Software. We are updating the list of fixed releases and adding the Software Checker. Our investigation has determined that the actors exploited two previously unknown issues. The attacker first exploited CVE-2023-20198 to gain initial access and issued a privilege 15 command to create a local user and password combination. This allowed the user to log in with normal user access. The attacker then exploited another component of the web UI feature, leveraging the new local user to elevate privilege to root and write the implant to the file system. Cisco has assigned CVE-2023-20273 to this issue. CVE-2023-20198 has been assigned a CVSS Score of 10.0. CVE-2023-20273 has been assigned a CVSS Score of 7.2. Both of these CVEs are being tracked by CSCwh87343.
