Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Improper access control (CVE-ID: CVE-2025-48734)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions to enum properties. If an application using Commons BeanUtils passes property paths from an external source directly to the getProperty() method of PropertyUtilsBean, an attacker can access the enum’s class loader via the “declaredClass” property available on all Java “enum” objects. Accessing the enum’s “declaredClass” allows remote attackers to access the ClassLoader and execute arbitrary code. The same issue exists with PropertyUtilsBean.getNestedProperty().
2) Improper input validation (CVE-ID: CVE-2025-8916)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the Security and Provisioning (Bouncy Castle Java Library) component in Oracle Essbase. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
3) Uncontrolled Recursion (CVE-ID: CVE-2025-48924)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the methods ClassUtils.getClass(...) can throw StackOverflowError on very long inputs. Because an Error is usually not handled by applications and libraries, a StackOverflowError could cause an application to stop. A remote attacker can trigger uncontrolled recursion and perform a denial of service (DoS) attack.
