IBM Virtualization Engine TS7700 is vulnerable to two potential denial of service conditions (CVE-2023-44487, CVE-2024-25026) and two instances of weaker than expected security (CVE-2023-50312, CVE-2023-46158) due to WebSphere Application Server Liberty. WebSphere Application Server Liberty is used by the TS7700 in the Management Interface. IBM Virtualization Engine TS7700 has addressed the applicable CVEs.
CVEID:CVE-2023-50312
**DESCRIPTION:**IBM WebSphere Application Server Liberty 17.0.0.3 through 24.0.0.2 could provide weaker than expected security for outbound TLS connections caused by a failure to honor user configuration. IBM X-Force ID: 274711.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/274711 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID:CVE-2023-46158
**DESCRIPTION:**IBM WebSphere Application Server Liberty 23.0.0.9 through 23.0.0.10 could provide weaker than expected security due to improper resource expiration handling. IBM X-Force ID: 268775.
CVSS Base score: 4.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268775 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID:CVE-2023-44487
**DESCRIPTION:**Multiple vendors are vulnerable to a denial of service, caused by a flaw in handling multiplexed streams in the HTTP/2 protocol. By sending numerous HTTP/2 requests and RST_STREAM frames over multiple streams, a remote attacker could exploit this vulnerability to cause a denial of service due to server resource consumption.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268044 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID:CVE-2024-25026
**DESCRIPTION:**IBM WebSphere Application Server 8.5, 9.0 and IBM WebSphere Application Server Liberty 17.0.0.3 through 24.0.0.4 are vulnerable to a denial of service, caused by sending a specially crafted request. A remote attacker could exploit this vulnerability to cause the server to consume memory resources. IBM X-Force ID: 281516.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/281516 for the current score.

IBM strongly recommends addressing the vulnerability now by visiting <https://tape.ibmrcl.enterpriseappointments.com/v2/> or contacting IBM Service at 1-800-IBM-SERV to arrange an upgrade to the latest microcode version followed by the installation of the appropriate VTD_EXEC as needed. Minimum microcode versions are shown below:
Machine Type | Model | Release | Fix |
---|---|---|---|
3957 | VED | R5.3 | Upgrade to 8.53.1.21 + VTD_EXEC.903 |
R5.4 | Upgrade to 8.54.1.27 + VTD_EXEC.904 | ||
3948 | VED | R5.3 | Upgrade to 8.53.1.21 + VTD_EXEC.903 |
R5.4 | Upgrade to 8.54.1.27 + VTD_EXEC.904 |
The minimum VTD_EXEC version is shown below:
VTD_EXEC Package | Version |
---|---|
VTD_EXEC.903 | v1.16 |
VTD_EXEC.904 | v1.04 |
Although IBM recommends that you upgrade to the fixes identified above, you can mitigate, but not eliminate the risk of these vulnerabilities by restricting physical and network access to the TS7700 to authorized users and IBM Service Personnel only.
