CVE-2025-29909
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. In versions 1.3.3 and prior, a heap buffer overflow vulnerability in CryptoLib's Crypto_TC_ApplySecurity() allows an attacker to craft a malicious TC frame that causes out-of-bounds memory writes. This can result in denial of service (DoS) or, under certain conditions, remote code execution (RCE). Any application or system that relies on CryptoLib for Telecommand (TC) processing and does not strictly validate incoming TC frames is at risk. This includes satellite ground stations or mission control software where attackers can inject malformed frames. A patch is available at commit c7e8a8745ff4b5e9bd7e500e91358e86d5abedcc.
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.
