CVE number – CVE-2019-10086
A vulnerability in Apache Commons Beanutils could allow an unauthenticated, remote attacker to perform unauthorized actions on an affected system.
The vulnerability exists because the affected software fails to suppress the class property in the PropertyUtilsBean class by default. An attacker could exploit this vulnerability by sending a request that submits malicious input to the affected system. A successful exploit could allow the attacker to use the class property of Java objects to get access to the classloader, which could be used to conduct further attacks.
Apache has confirmed the vulnerability and released software updates.
- To exploit this vulnerability, an attacker must send a request that submits malicious input to the targeted system, making exploitation more difficult in environments that restrict network access from untrusted sources.
- 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.
