Lifecycle Timeline
1DescriptionNVD
Multiple vulnerabilities in Cisco DNA Spaces Connector could allow an authenticated, local attacker to elevate privileges and execute arbitrary commands on the underlying operating system as root. These vulnerabilities are due to insufficient restrictions during the execution of affected CLI commands. An attacker could exploit these vulnerabilities by leveraging the insufficient restrictions during execution of these commands. A successful exploit could allow the attacker to elevate privileges from dnasadmin and execute arbitrary commands on the underlying operating system as root.
AnalysisAI
Multiple vulnerabilities in Cisco DNA Spaces Connector could allow an authenticated, local attacker to elevate privileges and execute arbitrary commands on the underlying operating system as root. Rated medium severity (CVSS 6.7), this vulnerability is low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. Multiple vulnerabilities in Cisco DNA Spaces Connector could allow an authenticated, local attacker to elevate privileges and execute arbitrary commands on the underlying operating system as root. These vulnerabilities are due to insufficient restrictions during the execution of affected CLI commands. An attacker could exploit these vulnerabilities by leveraging the insufficient restrictions during execution of these commands. A successful exploit could allow the attacker to elevate privileges from dnasadmin and execute arbitrary commands on the underlying operating system as root. Affected products include: Cisco Dna Spaces\.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
