Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2026-47011)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/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 Application Interface component in Siebel CRM Deployment. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.


2) Stack-based buffer overflow (CVE-ID: CVE-2025-5222)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the SRBRoot::addTag() function in genrb binary. A remote unauthenticated attacker can pass a specially crafted input to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Improper input validation (CVE-ID: CVE-2026-24308)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Core (Apache ZooKeeper) component in Oracle Communications Unified Assurance. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.


4) XML External Entity injection (CVE-ID: CVE-2026-24400)

CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')

CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to `org.assertj.core.util.xml.XmlStringPrettyFormatter`: the `toXmlDocument(String)` method initializes `DocumentBuilderFactory` with default settings, without disabling DTDs or external entities. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
