AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-2103 affects Infor SyteLine ERP, where hard-coded static cryptographic keys are used to encrypt stored credentials such as user passwords, database connection strings, and API keys.
These encryption keys are identical across all installations, meaning that an attacker who gains access to the application binary and database can decrypt all stored credentials universally.
The encryption uses a layered approach involving AES-256 with a fixed initialization vector and a legacy custom encryption, both of which provide weak cryptographic protection.
Because the keys are hard-coded and shared, there is no key rotation without redeploying binaries, and the encryption design leaks structural information, making it easier to decrypt the data.
How can this vulnerability impact me? :
This vulnerability allows an attacker with access to the application binary and database to decrypt all stored sensitive credentials, including user passwords, database connection strings, API keys, payment gateway passwords, session secrets, and URL signing keys.
Such a compromise can lead to full credential exposure, enabling unauthorized access to the application, databases, payment systems, and other integrated services.
Additionally, because the keys are identical across all installations, a single compromised copy of the software can be used to decrypt credentials universally, increasing the risk and scale of impact.
There is currently no vendor patch available, so the vulnerability remains exploitable.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by analyzing the Infor SyteLine ERP application binaries and database for the presence of hard-coded static cryptographic keys and encrypted credentials that use these keys. Specifically, reverse-engineering the application binary to identify the hard-coded Base64-encoded encrypted secrets and verifying if the encryption keys are identical across installations can confirm the vulnerability.
Detection involves checking for encrypted credentials stored as pairs of encrypted_key|encrypted_data in the database and attempting to decrypt them using the known static key derived from the application binary.
Suggested commands or steps include:
- Extract the application binary and use a tool like strings or a .NET decompiler (e.g., dotPeek, ILSpy) to locate hard-coded Base64-encoded keys.
- Query the database for stored credentials formatted as encrypted_key|encrypted_data.
- Attempt to Base64 decode and decrypt the stored credentials using the extracted static key and AES decryption with the known parameters (AES-256, PBKDF2-derived key, fixed salt and IV).
- Monitor for unusual access patterns or unauthorized attempts to access or export encrypted credentials from the database.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the application binaries and database to prevent attackers from obtaining the hard-coded keys and encrypted credentials.
Since no vendor patch is currently available, it is critical to implement strict access controls and monitoring to detect and prevent unauthorized access.
Additional recommended steps are:
- Limit database and application binary access to authorized personnel and processes only.
- Avoid exporting or backing up encrypted credentials without proper protection.
- Plan for a future update or patch from the vendor that replaces hard-coded keys with unique keys per installation and supports key rotation.
- Consider implementing compensating controls such as encrypting sensitive data with external key management systems (e.g., Windows DPAPI, Azure Key Vault, AWS KMS, or HSMs) if possible.
- Monitor for signs of credential compromise and prepare to rotate credentials once a fix is available.
