CVE Number – CVE-2018-1260
A vulnerability in Pivotal Software Spring Security OAuth could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to improper validation of user-supplied input processed by the affected software. An attacker could exploit the vulnerability by sending an authorization request that submits malicious input to the targeted authorization endpoint. An exploit could allow the attacker to execute arbitrary code on the targeted system when the resource owner is forwarded to the approval endpoint.
Pivotal Software has confirmed the vulnerability and released software updates.
To exploit this vulnerability, an attacker must make an authorization 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.
