ESI plugin does not have the limit for maximum inclusion depth, and that allows excessive memory consumption if malicious instructions are inserted.
Users can use a new setting for the plugin (--max-inclusion-depth) to limit it.
This issue affects Apache Traffic Server: from 10.0.0 through 10.0.5, from 9.0.0 through 9.2.10.
Users are recommended to upgrade to version 9.2.11 or 10.0.6, which fixes the issue.
A flaw was found in trafficserver. The Edge Side Includes (ESI) plugin lacks a limit on maximum inclusion depth, allowing a remote attacker to trigger excessive memory consumption by inserting malicious instructions. This condition occurs due to the plugin's inability to restrict the nesting of ESI includes, potentially leading to a denial of service. The vulnerability is triggered via a crafted ESI request.
ΠΡΡΠ΅Ρ
This issue is rated as Important because it allows a remote, unauthenticated attacker to impact the availability of the service without requiring user interaction. While it requires a specific plugin to be enabled, ESI is a common feature for environments that serve dynamic content. The vulnerability does not lead to a compromise of confidentiality or integrity, preventing a "Critical" rating. Apache Traffic Server is primarily available in Red Hat environments through the community-supported EPEL repository, which is a key factor in this assessment.
