CVE-2022-30910 Magic H3C R100 R100V100R005 had a stack overflow vulnerability via the GO parameter.

CVE-2022-30910 Magic H3C R100 R100V100R005 had a stack overflow vulnerability via the GO parameter.

The researcher discovered that the GO parameter was not properly sanitized, allowing an attacker to execute a stack buffer overflow and execute arbitrary code on the victim’s system. The researcher reported this vulnerability to Cisco. Cisco confirmed the vulnerability and released a patch. End users should be strict about following vulnerability management procedures, such as updating software and using strong passwords.

Cisco DPEs are advised to consider the following when applying the patch: — Restrict access to the interface where the vulnerable module is installed. — Restrict access to the vulnerable module by logging into the device and disabling access for the vulnerable module. — Restrict access to the vulnerable module by using a password. — Restrict access to the vulnerable module by using an access control list or by using a firewall. — Restrict access to the vulnerable module by using a role-based access control model. — Restrict access to the vulnerable module by using a least privilege model. — Restrict access to the vulnerable module by using a separation of duties model.
