Is this vulnerability remotely exploitable?

It can be, but indirectly. Attackers typically need the ability to obtain ciphertexts produced by the vulnerable encryption scheme (for example, by reading configuration files, logs, or repository-stored encrypted values). Remote exploitability depends on whether such ciphertexts are exposed through network-accessible services or repositories.

What level of access does an attacker need to take advantage of this issue?

An attacker generally needs read access to data encrypted via Jervis using the deterministic-IV scheme. In some scenarios, the ability to influence plaintexts or trigger multiple encryptions with the same passphrase can increase the impact or feasibility of attacks.

What is the safest general fix pattern for this kind of problem?

The safest pattern is to adopt a well-vetted encryption scheme that: - Uses a cryptographically secure random IV or nonce for every encryption operation. - Separately derives keys from passphrases using a standard key-derivation function. - Employs authenticated encryption modes to provide both confidentiality and integrity.
