Null Byte Interaction Error (Poison Null Byte)

Overview Affected versions of this package are vulnerable to Null Byte Interaction Error Poison Null Byte due to inadequate validation of domain name labels and lengths in the encodeDomainName and decodeDomainName components. An attacker can cause DNS cache poisoning, bypass domain validation, or...

CVE-2022-25218

The use of the RSA algorithm without OAEP, or any other padding scheme, in telnetdstartup, allows an unauthenticated attacker on the local area network to achieve a significant degree of control over the "plaintext" to which an arbitrary blob of ciphertext will be decrypted by OpenSSL's...

Design/Logic Flaw

A null byte interaction error has been discovered in the code that the telnetdstartup daemon uses to construct a pair of ephemeral passwords that allow a user to spawn a telnet service on the router, and to ensure that the telnet service persists upon reboot. By means of a crafted exchange of UDP...

CVE-2022-25219

CVE-2022-25219/25218 describe a flaw in the telnetd_startup routine where the use of RSA without padding (or OAEP) enables an unauthenticated attacker on the local network to influence the decrypted plaintext via crafted UDP packets, potentially gaining a root shell. The 25219 issue centers on a ...
