GHSA-r9w3-57w2-gch2
No affected components available
Description
Following Admin APIs in Ory Hydra are vulnerable to SQL injection due to flaws in its pagination implementation:
- listOAuth2Clients
- listOAuth2ConsentSessions
- listTrustedOAuth2JwtGrantIssuers
Pagination tokens are encrypted using the secret configured in secrets.pagination. If this value is not set, Hydra falls back to using secrets.system. An attacker who knows this secret can craft their own tokens, including malicious tokens that lead to SQL injection.
Preconditions
This issue can be exploited when the following conditions are met:
- One or more admin APIs listed above are directly or indirectly accessible to the attacker
- The attacker can pass a raw pagination token to the affected API
- The configuration value
secrets.paginationis set and known to the attacker, orsecrets.paginationis not set andsecrets.systemis known to the attacker
Impact
An attacker can execute arbitrary SQL queries through forged pagination tokens.
Mitigation
As a first line of defense, immediately configure a custom value for secrets.pagination by generating a cryptographically secure random secret, for example:
openssl rand -base64 32
Next, upgrade Hydra to the fixed version as soon as possible.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs high-level or administrative privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
