In 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. AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. A OS Command Injection vulnerability exists in Node.js versions <14.20.0, <16.16.0, <18.5.0 due to an insufficient IsAllowedHost check that can easily be bypassed because IsIPAddress does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks. The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly parse and validate Transfer-Encoding headers and can lead to HTTP Request Smuggling (HRS). The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS). A cryptographic vulnerability exists on Node.js on linux in versions of 18.x prior to 18.40.0 which allowed a default path for openssl.cnf that might be accessible under some circumstances to a non-admin user instead of /etc/ssl as was the case in versions prior to the upgrade to OpenSSL 3. Node.js made calls to EntropySource() in SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc. However, it does not check the return value, it assumes EntropySource() always succeeds, but it can (and sometimes will) fail. The llhttp parser in the http module in Node.js v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling. An authenticated remote attacker with access to the Web Based Management (443/tcp) of the affected product, could potentially read and write arbitrary files from and to the device's file system. An attacker might leverage this to trigger remote code execution on the affected component. An authenticated remote attacker with access to the Web Based Management (443/tcp) of the affected product as well as with access to the SFTP server of the affected product (22/tcp), could potentially read and write arbitrary files from and to the device's file system. An attacker might leverage this to trigger remote code execution on the affected component. An authenticated remote attacker with access to the Web Based Management (443/tcp) of the affected product, could potentially inject commands into the dhcpd configuration of the affected product. An attacker might leverage this to trigger remote code execution on the affected component.
