Changes with Apache 2.4.54
*) SECURITY: CVE-2022-31813: mod_proxy X-Forwarded-For dropped by
hop-by-hop mechanism (cve.mitre.org)
Apache HTTP Server 2.4.53 and earlier may not send the
X-Forwarded-* headers to the origin server based on client side
Connection header hop-by-hop mechanism.
This may be used to bypass IP based authentication on the origin
server/application.

Gaetan Ferry (Synacktiv) for reporting this issue
*) SECURITY: CVE-2022-30556: Information Disclosure in mod_lua with
websockets (cve.mitre.org)
Apache HTTP Server 2.4.53 and earlier may return lengths to
applications calling r:wsread() that point past the end of the
storage allocated for the buffer.

Ronald Crane (Zippenhop LLC) for reporting this issue
*) SECURITY: CVE-2022-30522: mod_sed denial of service
(cve.mitre.org)
If Apache HTTP Server 2.4.53 is configured to do transformations
with mod_sed in contexts where the input to mod_sed may be very
large, mod_sed may make excessively large memory allocations and
trigger an abort.

Security Research team
*) SECURITY: CVE-2022-29404: Denial of service in mod_lua
r
arsebody (cve.mitre.org)
In Apache HTTP Server 2.4.53 and earlier, a malicious request to
a lua script that calls r
arsebody(0) may cause a denial of
service due to no default limit on possible input size.

Ronald Crane (Zippenhop LLC) for reporting this issue
*) SECURITY: CVE-2022-28615: Read beyond bounds in
ap_strcmp_match() (cve.mitre.org)
Apache HTTP Server 2.4.53 and earlier may crash or disclose
information due to a read beyond bounds in ap_strcmp_match()
when provided with an extremely large input buffer. While no
code distributed with the server can be coerced into such a
call, third-party modules or lua scripts that use
ap_strcmp_match() may hypothetically be affected.

Ronald Crane (Zippenhop LLC) for reporting this issue
*) SECURITY: CVE-2022-28614: read beyond bounds via ap_rwrite()
(cve.mitre.org)
The ap_rwrite() function in Apache HTTP Server 2.4.53 and
earlier may read unintended memory if an attacker can cause the
server to reflect very large input using ap_rwrite() or
ap_rputs(), such as with mod_luas r
uts() function.

Ronald Crane (Zippenhop LLC) for reporting this issue
*) SECURITY: CVE-2022-28330: read beyond bounds in mod_isapi
(cve.mitre.org)
Apache HTTP Server 2.4.53 and earlier on Windows may read beyond
bounds when configured to process requests with the mod_isapi
module.

Ronald Crane (Zippenhop LLC) for reporting this issue
*) SECURITY: CVE-2022-26377: mod_proxy_ajp: Possible request
smuggling (cve.mitre.org)
Inconsistent Interpretation of HTTP Requests ('HTTP Request
Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server
allows an attacker to smuggle requests to the AJP server it
forwards requests to. This issue affects Apache HTTP Server
Apache HTTP Server 2.4 version 2.4.53 and prior versions.

*) mod_ssl: SSLFIPS compatible with OpenSSL 3.0. PR 66063.
[Petr Sumbera <petr.sumbera oracle.com>, Yann Ylavic]
*) mod_proxy_http: Avoid 417 responses for non forwardable 100-continue.
PR 65666. [Yann Ylavic]
*) mod_md: a bug was fixed that caused very large MDomains
with the combined DNS names exceeding ~7k to fail, as
request bodies would contain partially wrong data from
uninitialized memory. This would have appeared as failure
in signing-up/renewing such configurations.

transmission delays. PR 66019. [Yann Ylavic]
*) MPM event: Fix accounting of active/total processes on ungraceful restart,
PR 66004 (follow up to PR 65626 from 2.4.52). [Yann Ylavic]
*) core: make ap_escape_quotes() work correctly on strings
with more than MAX_INT/2 characters, counting quotes double.

*) mod_md: the `MDCertificateAuthority` directive can take more than one URL/name of
an ACME CA. This gives a failover for renewals when several consecutive attempts
to get a certificate failed.
A new directive was added: `MDRetryDelay` sets the delay of retries.
A new directive was added: `MDRetryFailover` sets the number of errored
attempts before an alternate CA is selected for certificate renewals.
[Stefan Eissing]
*) mod_http2: remove unused and insecure code. Fixes PR66037.
Thanks to Ronald Crane (Zippenhop LLC) for reporting this.
[Stefan Eissing]
*) mod_proxy: Add backend port to log messages to
ease identification of involved service. [Rainer Jung]
*) mod_http2: removing unscheduling of ongoing tasks when
connection shows potential abuse by a client. This proved
counter-productive and the abuse detection can false flag
requests using server-side-events.
Fixes <
https://github.com/icing/mod_h2/issues/231>.
[Stefan Eissing]
*) mod_md: Implement full auto status ("key: value" type status output).
Especially not only status summary counts for certificates and
OCSP stapling but also lists. Auto status format is similar to
what was used for mod_proxy_balancer.
[Rainer Jung]
*) mod_md: fixed a bug leading to failed transfers for OCSP
stapling information when more than 6 certificates needed
updates in the same run. [Stefan Eissing]
*) mod_proxy: Set a status code of 502 in case the backend just closed the
connection in reply to our forwarded request. [Ruediger Pluem]
*) mod_md: a possible NULL pointer deref was fixed in
the JSON code for persisting time periods (start+end).
Fixes #282 on mod_md's github.
Thanks to @marcstern for finding this. [Stefan Eissing]
*) mod_heartmonitor: Set the documented default value
"10" for HeartbeatMaxServers instead of "0". With "0"
no shared memory slotmem was initialized. [Rainer Jung]
*) mod_md: added support for managing certificates via a
local tailscale daemon for users of that secure networking.
This gives trusted certificates for tailscale assigned
domain names in the *.ts.net space.
