Description

This security bulletin contains information about 6 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2026-46980)

CWE-ID: CWE-20 - Improper input validation

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 Mobile component in Oracle Utilities Network Management System. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.


2) Improper input validation (CVE-ID: CVE-2026-46948)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 4.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the Security component in Oracle Utilities Network Management System. A remote authenticated user can exploit this vulnerability to read and manipulate data.


3) Improper handling of highly compressed data (CVE-ID: CVE-2026-21441)

CWE-ID: CWE-409 - Improper Handling of Highly Compressed Data (Data Amplification)

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


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the application does not properly handle highly compressed data when sending HTTP redirect responses. A remote attacker can multiple large requests to the application, consume all available CPU and memory resources and perform a denial of service attack.


4) Improper input validation (CVE-ID: CVE-2026-46981)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/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 Mobile component in Oracle Utilities Network Management System. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.


5) 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.


6) Out-of-bounds read (CVE-ID: CVE-2025-58050)

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

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a boundary condition in the PCRE2 regular expression matching engine during handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. A remote attacker can pass specially crafted input to the application, trigger an out-of-bounds read error and read contents of memory on the system.
