Vulnerability Details
CVEID: CVE-2017-9735
DESCRIPTION: Jetty could allow a remote attacker to obtain sensitive information, caused by a timing channel flaw in util/security/Password.java. By observing elapsed times before rejection of incorrect passwords, an attacker could exploit this vulnerability to obtain access information.

CVEID: CVE-2017-7658
DESCRIPTION: Eclipse Jetty is vulnerable to HTTP request smuggling, caused by a flaw when handling more than one Content-Length headers. By sending a specially-crafted request, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/145522 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2017-7657
DESCRIPTION: Eclipse Jetty is vulnerable to HTTP request smuggling, caused by improper handling of Chunked Transfer-Encoding chunk size. By sending a specially-crafted request, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/145521 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2021-41033
DESCRIPTION: Eclipse Equinox is vulnerable to a man-in-the-middle attack, caused by the use unencrypted HTTP communication in p2 repos. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to alter the local installation, and execute arbitrary code on the system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/209186 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2021-34428
DESCRIPTION: Eclipse Jetty could allow a physical attacker to bypass security restrictions, caused by a session ID is not invalidated flaw when an exception is thrown from the SessionListener#sessionDestroyed() method. By gaining access to the application on the shared computer, an attacker could exploit this vulnerability to bypass access restrictions.
CVSS Base score: 3.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/204227 for the current score.

Affected Products and Versions
| Affected Product(s) | Version(s) |
| SDI | 7.2.0 |
| IBM Security Directory Integrator | 10.0.0 |
Remediation/Fixes
IBM strongly recommends that customers update their systems promptly.
IBM Tivoli Directory Integrator 7.2 customers must move up to the IBM Security Directory Integrator 10.0 product.
Information about migration is documented here: https://www.ibm.com/docs/en/svdi/10.0.0?topic=administering-migrating
To install IBM Security Directory Integrator 10.0 On-Prem software stack please download Passport Advantage product number G0BFVML.
To install IBM Security Directory Integrator 10.0 Container, use the following commands:
docker pull icr.io/isvdi/verify-directory-integrator:latest
docker pull icr.io/isvdi/verify-directory-integrator-scim:latest
docker pull icr.io/isvdi/verify-directory-integrator-fds:latest
The container images are listed at https://www.ibm.com/docs/en/svdi/10.0.0?topic=containers-images.
Workarounds and Mitigations
Eclipse Jetty Server provides Federated Directory Server Console and IBM Security Directory Integrator Dashboard components. If you are not using any of these components, Eclipse Jetty can be safely disabled.
Steps to disable the Eclipse Jetty are as follows:
- Stop the Security Directory Integrator server process.
- Set dashboard.on=false and api.rest.on=false in the solution.properties file within the solution directory.
- Start the Security Directory Integrator server process.
After making this change, the system environment becomes non-vulnerable to the vulnerabilities mentioned in this bulletin and Security Directory Integrator 7.2 can be used.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
