CVE-2025-29911
No affected components available
CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. A critical heap buffer overflow vulnerability was identified in the Crypto_AOS_ProcessSecurity function of CryptoLib versions 1.3.3 and prior. This vulnerability allows an attacker to trigger a Denial of Service (DoS) or potentially execute arbitrary code (RCE) by providing a maliciously crafted AOS frame with an insufficient length. The vulnerability lies in the function Crypto_AOS_ProcessSecurity, specifically during the processing of the Frame Error Control Field (FECF). The affected code attempts to read from the p_ingest buffer at indices current_managed_parameters_struct.max_frame_size - 2 and current_managed_parameters_struct.max_frame_size - 1 without verifying if len_ingest is sufficiently large. This leads to a heap buffer overflow when len_ingest is smaller than max_frame_size. As of time of publication, no known patched versions exist.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
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.
