VAR-201708-0235

Vulnerability from variot - Updated: 2025-04-20 23:34

Improper Verification of Cryptographic Signature in AVM FRITZ!Box 6810 LTE after firmware 5.22, FRITZ!Box 6840 LTE after firmware 5.23, and other models with firmware 5.50. AVM FRITZ!Box 6810 LTE and 6840 LTE Contains a code injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. AVMFRITZ! Box6810LTE and FRITZ! Box6840 LTE are router products of the German AVM company. A code injection vulnerability exists in AVMFRITZ!Box6810LTE and FRITZ!Box6840LTE due to a program failing to properly verify the cryptographic signature. A remote attacker can exploit this vulnerability to inject and execute malicious code. There is a code injection vulnerability in AVM FRITZ!Box 6810 LTE and FRITZ!Box 6840 LTE
