SB2026111022 - Multiple vulnerabilities in Enterprise Manager Base Platform

Description

This security bulletin contains information about 7 vulnerabilities.

1) Input validation error (CVE-ID: CVE-2026-1225)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 1.8 [CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L]

The vulnerability allows a local privileged user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A local privileged user can instantiate classes already present on the class path by compromising an existing logback configuration file. The instantiation of a potentially malicious Java class requires that said class is present on the user's class-path. In addition, the attacker must have write access to a configuration file.

2) Improper input validation (CVE-ID: CVE-2026-101511)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote authenticated user to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Metadata Plugin component in Oracle Enterprise Manager Base Platform. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.

3) Improper input validation (CVE-ID: CVE-2026-101524)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The vulnerability exists due to improper input validation within the Security Framework component in Oracle Enterprise Manager Base Platform. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.

4) Improper input validation (CVE-ID: CVE-2026-101527)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local authenticated user to execute arbitrary code.

The vulnerability exists due to improper input validation within the Enterprise Manager Install component in Oracle Enterprise Manager Base Platform. A local authenticated user can exploit this vulnerability to execute arbitrary code.

5) Deserialization of Untrusted Data (CVE-ID: CVE-2026-54512)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to instantiate arbitrary classes.

The vulnerability exists due to deserialization of untrusted data in DatabindContext._resolveAndValidateGeneric() and PolymorphicTypeValidator handling when processing polymorphic type identifiers with generic parameters during deserialization. A remote attacker can supply a specially crafted type identifier and JSON data to instantiate arbitrary classes.

Only applications that accept untrusted JSON and have polymorphic typing enabled while relying on a configured PolymorphicTypeValidator allow-list are affected.

6) Improper access control (CVE-ID: CVE-2025-48734)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]

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().

7) Improper input validation (CVE-ID: CVE-2026-101518)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote authenticated user to execute arbitrary code.

The vulnerability exists due to improper input validation within the Agent Next Gen component in Oracle Enterprise Manager Base Platform. A remote authenticated user can exploit this vulnerability to execute arbitrary code.
