Effective 2019 Sep 15, Cisco will no longer publish non-Cisco product alerts. Cisco will continue to publish Security Advisories to address third-party software vulnerabilities per the Cisco Security Vulnerability Policy.
A vulnerability in the Django App component of Splunk could allow an authenticated, remote attacker to conduct a path traversal attack on a targeted system.
The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by sending a request that submits malicious directory traversal characters to the targeted system. A successful exploit could allow the attacker to download arbitrary files from the Django App component of the affected application, which could be used to conduct further attacks.
Splunk has confirmed the vulnerability and released software updates.
To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement may reduce the likelihood of a successful exploit.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Administrators are advised to run both firewall and antivirus applications to minimize the potential of inbound and outbound threats.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators can help protect affected systems from external attacks by using a solid firewall strategy.
Administrators are advised to monitor affected systems.
