haproxy-boshrelease: Authentication Bypass by Spoofing
CVE-2024-37082 is a critical-severity authentication bypass by spoofing vulnerability in haproxy-boshrelease from Cloud Foundry, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 0.299.0 as the first without the flaw, so updating haproxy-boshrelease to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.55% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update haproxy-boshrelease to 0.299.0 or a later version.
- Update haproxy-boshrelease to 0.299.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |

Official description
When deploying Cloud Foundry together with the haproxy-boshrelease and using a non default configuration, it might be possible to craft HTTP requests that bypass mTLS authentication to Cloud Foundry applications. You are affected if you have route-services enabled in routing-release and have configured the haproxy-boshrelease property “ha_proxy.forwarded_client_cert” to “forward_only_if_route_service”.

The underlying weakness: Authentication Bypass by Spoofing
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
