CVE-2022-2068
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUser input reaches a shell or system command without being fully separated from the command itself, so an attacker can append their own instructions. Because these run with the application's privileges, it often means full control of the host. The lasting fix is to avoid the shell entirely — call APIs directly and pass arguments as data, never as concatenated strings.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.01.0.2zf1.1.1p
OpenSSL 3.0.4 (for 3.0.x branch), OpenSSL 1.1.1p (for 1.1.1 branch), or OpenSSL 1.0.2zf (for 1.0.2 branch)
- 1. Identify the current OpenSSL version by running: openssl version -a
- 2. Determine which version branch is installed (1.0.2x, 1.1.1x, or 3.0.x)
- 3. For OpenSSL 3.0.x users: Upgrade to version 3.0.4 or later using the system's package manager (e.g., apt-get update && apt-get install openssl or yum update openssl)
- 4. For OpenSSL 1.1.1x users: Upgrade to version 1.1.1p or later
- 5. For OpenSSL 1.0.2x users: Upgrade to version 1.0.2zf or later
- 6. Verify the upgrade was successful by running: openssl version -a
- 7. As an additional hardening measure, replace usage of the obsolete c_rehash script with the modern OpenSSL rehash command-line tool
