Description
Summary
This handler wrapper https://github.com/open-telemetry/opentelemetry-go-contrib/blob/5f7e6ad5a49b45df45f61a1deb29d7f1158032df/instrumentation/net/http/otelhttp/handler.go#L63-L65
out of the box adds labels
http.user_agent
http.method
that have unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent to it.
Details
HTTP header User-Agent or HTTP method for requests can be easily set by an attacker to be random and long. The library internally uses httpconv.ServerRequest that records every value for HTTP method and User-Agent.
PoC
Send many requests with long randomly generated HTTP methods or/and User agents (e.g. a million) and observe how memory consumption increases during it.
Impact
In order to be affected, the program has to configure a metrics pipeline, use otelhttp.NewHandler wrapper, and does not filter any unknown HTTP methods or User agents on the level of CDN, LB, previous middleware, etc.
Others
It is similar to already reported vulnerabilities
- GHSA-5r5m-65gx-7vrh (open-telemetry/opentelemetry-go-contrib)
- GHSA-cg3q-j54f-5p7p (prometheus/client_golang)
Workaround for affected versions
As a workaround to stop being affected otelhttp.WithFilter() can be used, but it requires manual careful configuration to not log certain requests entirely.
For convenience and safe usage of this library, it should by default mark with the label
unknown
non-standard HTTP methods and User agents to show that such requests were made but do not increase cardinality. In case someone wants to stay with the current behavior, library API should allow to enable it.The other possibility is to disable HTTP metrics instrumentation by passing
otelhttp.WithMeterProvider
option withnoop.NewMeterProvider
.Solution provided by upgrading
In PR open-telemetry/opentelemetry-go-contrib#4277, released with package version 0.44.0, the values collected for attribute
http.request.method
were changed to be restricted to a set of well-known values and other high cardinality attributes were removed.References

Description
Withdrawn Advisory
This advisory has been withdrawn because it was incorrectly attributed to runc. Please see the issue here for more information.
Original Description
A flaw was found in cri-o, where an arbitrary systemd property can be injected via a Pod annotation. Any user who can create a pod with an arbitrary annotation may perform an arbitrary action on the host system. This issue has its root in how runc handles Config Annotations lists.

Description
Impact
runc 1.1.13 and earlier as well as 1.2.0-rc2 and earlier can be tricked into
creating empty files or directories in arbitrary locations in the host
filesystem by sharing a volume between two containers and exploiting a race
with os.MkdirAll. While this can be used to create empty files, existing
files will not be truncated.An attacker must have the ability to start containers using some kind of custom
volume configuration. Containers using user namespaces are still affected, but
the scope of places an attacker can create inodes can be significantly reduced.
Sufficiently strict LSM policies (SELinux/Apparmor) can also in principle block
this attack -- we suspect the industry standard SELinux policy may restrict
this attack's scope but the exact scope of protection hasn't been analysed.This is exploitable using runc directly as well as through Docker and
Kubernetes.The CVSS score for this vulnerability is
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N (Low severity, 3.6).Workarounds
Using user namespaces restricts this attack fairly significantly such that the
attacker can only create inodes in directories that the remapped root
user/group has write access to. Unless the root user is remapped to an actual
user on the host (such as with rootless containers that don't use
/etc/sub[ug]id), this in practice means that an attacker would only be able to
create inodes in world-writable directories.A strict enough SELinux or AppArmor policy could in principle also restrict the
scope if a specific label is applied to the runc runtime, though we haven't
thoroughly tested to what extent the standard existing policies block this
attack nor what exact policies are needed to sufficiently restrict this attack.Patches
Fixed in runc v1.1.14 and v1.2.0-rc3.
