      <body xmlns="http://www.w3.org/1999/xhtml">
	<p>In ServerCo getssl version 2.49 and prior, the ACME challenge token
	returned to the client was not strictly validated against RFC 8555
	before being used in challenge-file handling, allowing a maliciously
	crafted token to influence local path/filename usage during
	validation. An attacker who can supply ACME challenge responses to
	getssl (for example, a malicious or compromised CA endpoint, or an
	on-path adversary able to tamper with that response path) could
	exploit this to achieve unauthorized file write/path traversal
	effects, usually with elevated privileges, ultimately allowing for
	remote command injection. This issue appears related in spirit to
	CVE-2023-38198, and is an instance of CWE-73, "External control of
	file name or path." Other ACME shell script handlers may be affected
	by similar issues.</p>
