Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2022-21383)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote authenticated user to perform service disruption.

The vulnerability exists due to improper input validation within the Log component in Oracle Enterprise Session Border Controller. A remote authenticated user can exploit this vulnerability to perform service disruption.


2) Off-by-one (CVE-ID: CVE-2021-23017)

CWE-ID: CWE-193 - Off-by-one Error

CVSSv4: 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/E:P/U:Amber


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

The vulnerability exists due to an off-by-one error within the ngx_resolver_copy() function when processing DNS responses. A remote attacker can trigger an off-by-one error, write a dot character (‘.’, 0x2E) out of bounds in a heap allocated buffer and execute arbitrary code on the system.

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

The vulnerability can be triggered by a DNS response in reply to a DNS request from nginx when the resolver primitive is configured. A specially crafted packet allows overwriting the least significant byte of next heap chunk metadata with 0x2E.


3) Improper input validation (CVE-ID: CVE-2022-21381)

CWE-ID: CWE-20 - Improper input validation

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


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

The vulnerability exists due to improper input validation within the WebUI component in Oracle Enterprise Session Border Controller. A remote authenticated user can exploit this vulnerability to read and manipulate data.


4) Improper input validation (CVE-ID: CVE-2022-21382)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote authenticated user to manipulate data.

The vulnerability exists due to improper input validation within the WebUI component in Oracle Enterprise Session Border Controller. A remote authenticated user can exploit this vulnerability to manipulate data.
