Inspur NF5266M5 through 3.21.2 and other server M5 devices allow remote code execution via administrator privileges. The Baseboard Management Controller (BMC) program of INSPUR server is weak in checking the firmware and lacks the signature verification mechanism, the attacker who obtains the administrator's rights can control the BMC by inserting malicious code into the firmware program and bypassing the current verification mechanism to upgrade the BMC.
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
https://cwe.mitre.org/data/definitions/347.html →Open in CWE collection →An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.
