SB2026060513 - Multiple vulnerabilities in Communications Unified Assurance

Description

This security bulletin contains information about 8 vulnerabilities.

1) Out-of-bounds read (CVE-ID: CVE-2026-34059)

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

CVSSv4: 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/E:U/U:Green

The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to a heap over-read in mod_proxy_ajp ajp_parse_data() when processing AJP messages from a backend server. A remote attacker can send a specially crafted AJP message to disclose sensitive information.

Exploitation requires Apache HTTP Server to connect to an untrusted or compromised AJP backend server.

2) Heap-based buffer overflow (CVE-ID: CVE-2026-25646)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 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/E:U/U:Amber

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

The vulnerability exists due to a boundary error within the png_set_quantize() API function. A remote attacker can pass specially crafted PNG image to the application, trigger a heap-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: 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/E:U/U:Green

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) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2026-34487)

CWE-ID: CWE-532 - Information Exposure Through Log Files

CVSSv4: 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/E:U/U:Green

The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to insertion of sensitive information into log output in the cloud membership for clustering component when writing log messages. A remote attacker can trigger log entries that expose the Kubernetes bearer token to disclose sensitive information.

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

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

CVSSv4: 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/E:U/U:Green

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.

6) Code Injection (CVE-ID: CVE-2026-41044)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: 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/E:U/U:Green

The vulnerability allows a remote user to execute arbitrary code.

The vulnerability exists due to improper input validation and code injection in the admin web console and DestinationView MBean when processing a malicious broker name and triggering VM transport creation. A remote user can construct a malicious broker name and send a message through the DestinationView MBean to execute arbitrary code.

Exploitation requires access to the admin web console and the DestinationView MBean exposed by Jolokia.

7) Stack-based buffer overflow (CVE-ID: CVE-2025-15467)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber

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

The vulnerability exists due to a boundary error when parsing CMS AuthEnvelopedData structures that use AEAD ciphers such as AES-GCM, the IV (Initialization Vector) encoded in the ASN.1 parameters. A remote attacker can supply a specially crafted CMS message with an oversized IV, 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.

8) Improper input validation (CVE-ID: CVE-2026-33557)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber

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

The vulnerability exists due to improper input validation within the Message Bus (Apache Kafka) component in Oracle Communications Unified Assurance. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
