Badge of Shame: Breaking into Secure Facilities with OSDP

Security

Discover the vulnerabilities of the OSDP protocol, a widely used security standard, and learn how to break into secure facilities, highlighting the lack of encryption, poor configuration, and exploitable design flaws.

Key takeaways

The OSDP protocol is not as secure as it seems, as it allows unencrypted traffic and is vulnerable to downgrade attacks.
The protocol lacks encryption and relies on a master key, making it easily exploitable.
A reader can be configured to support encryption, but it’s not enabled by default.
An attacker can capture the encryption key by compromising the reader or controller.
Poor configuration and lack of encryption can lead to vulnerabilities in the system.
The protocol does not provide mutual authentication, making it susceptible to replay attacks.
An attacker can force communication to use encryption, but this will not guarantee security.
The IV (initialization vector) can be predicted using the birthday problem, making it possible to decrypt encrypted data.
It’s recommended to never trust that the communication is encrypted and to always verify the encryption status.
Misconfigured readers can be exploited to gain unauthorized access to the system.
The protocol is vulnerable to install mode attacks, which allow an attacker to set up a reader in install mode and gain access to the system.
Poor documentation and lack of setup guidance can lead to misconfigurations and vulnerabilities.
An attacker can capture the keyset command and decrypt the data using the extracted encryption key.
Authentication is lacking in the protocol, making it vulnerable to attacks.
The SCBKD (secure channel base key default) is the default encryption key used in the protocol.
It’s recommended to use encryption and verify the encryption status to ensure security.
Poor implementation and lack of setup guidance can lead to vulnerabilities in the system.
