Synopsis
The remote device is missing a vendor-supplied security patch
Description
According to its self-reported version, Cisco IOS is affected by multiple vulnerabilities:
- Multiple parameter injection vulnerabilities in the Cisco IOx application hosting environment. Due to incomplete sanitization of parameters that are part of an application package, an authenticated, remote attacker can use a specially crafted application package to execute arbitrary code as root on the underlying host operating system. (CVE-2022-20718, CVE-2022-20719, CVE-2022-20723)
- A path traversal vulnerability in the Cisco IOx application hosting environment. Due to a missing real path check, an authenticated remote attacker can create a symbolic link within a deployed application to read or execute arbitrary code as root on the underlying host operating system. (CVE-2022-20720)
- A race condition in the Cisco IOx application hosting environment can allow an unauthenticated remote attacker to bypass authentication and impersonate another authenticated user session. (CVE-2022-20724)
- A cross-site scripting vulnerability in the web-based Local Manager interface of the Cisco IOx application hosting environment can allow a remote attacker, authenticated with Local Manager credentials, to inject malicious code into the system settings tab. (CVE-2022-20725)
- A denial of service vulnerability in the Cisco IOx application host environment of Cisco 809 and 829 integrated service routers, Cisco CGR 1000 Compute Modules and Cisco IC3000 Industrial Compute Gateways. Due to insufficient error handling of socket operations, an unauthenticated, remote attacker can cause the IOx web sever to stop processing requests. (CVE-2022-20726)
- A privilege escalation vulnerability in the Cisco IOx application hosting environment due to improper input validation. An authenticated, local attacker can modify application content while the application is loading to gain privileges equivalent to the root user. (CVE-2022-20727)
- Multiple vulnerabilities in the Cisco IOx application hosting environment. Due to insufficient path validation, an authenticated, remote attacker can send a specially requested command to the Cisco IOx API to read the contents of any file on the host device filesystem. (CVE-2022-20721, CVE-2022-20722)
