| CVE-2026-123999 | 1 Nasajpl | 1 Iondtn | 2026-11-11 | 7.5 High |
| NASA JPL ION-DTN 3.6.2 through 4.2.0 contains a heap-based buffer overflow in the Network Management daemon (nm_mgr) string-formatting logic that allows a malicious or misconfigured agent to trigger an out-of-bounds write by sending deeply nested AMP payloads that exceed fixed-size buffer allocations through unbounded strcat operations. Attackers can transmit oversized AMP reports, tables, or macros over the UDP CLA/AMP path or trigger the flaw locally via interactive UI rendering to crash nm_mgr and cause a denial of service halting telemetry collection and operator visibility. | ||||
| CVE-2026-124000 | 1 Nasajpl | 1 Iondtn | 2026-11-11 | 5.3 Medium |
| NASA JPL ION-DTN 2.1.0 through 4.2.0 contains a heap buffer under-allocation vulnerability in the Asynchronous Message Service daemon (amsd) that allows a rogue or misconfigured peer to trigger an out-of-bounds write by sending crafted Meta-AMS (MAMS) configuration management messages that are processed without cryptographic authentication. Attackers can exploit the insufficient buffer size calculation for the internal state-event object to crash the active Configuration Server thread, causing a denial of service and potentially destabilizing subsequent shared-memory allocations in amsd. | ||||
| CVE-2026-124001 | 1 Nasajpl | 1 Iondtn | 2026-11-11 | 8.1 High |
| NASA JPL ION-DTN 2.2.1b through 4.2.0 contains an integer overflow vulnerability in the Datagram Retransmission (DGR) convergence layer that allows attackers to corrupt heap memory by sending a maliciously crafted 64-bit svcDataLength value that wraps a 32-bit allocation size calculation. Attackers can exploit the dgr_receive API's unchecked memcpy operation using synthetic datagrams or DGR traffic over internal IPC or custom transports to trigger an out-of-bounds write, leading to denial of service or potential remote code execution. | ||||
| CVE-2026-75584 | 1 Nasajpl | 1 Iondtn | 2026-09-18 | 7.5 High |
| ION-DTN before 4.2.1-a.1 contains a denial of service vulnerability that allows unauthenticated remote attackers to crash the ION process by sending a BPv7 bundle with a zero-length payload. The canonicalizePayloadBlock() function in bpsec_util.c passes bundle->payload.length to zco_clone() without validating it against zero, causing a failed CHKZERO assertion that triggers sm_Abort() and terminates the process with SIGABRT before any HMAC verification occurs, requiring no valid key or credential to exploit. | ||||
| CVE-2026-84484 | 1 Nasajpl | 1 Iondtn | 2026-09-04 | 7.5 High |
| ION-DTN versions before 4.2.0 contain an out-of-bounds read vulnerability in the decodeSdnv function that allows unauthenticated remote attackers to read memory by sending truncated SDNV values. Attackers can send a UDP datagram to the LTP link service input port with a truncated SDNV to trigger reads up to nine bytes past buffer boundaries and underflow byte counters. | ||||
| CVE-2024-54130 | 1 Nasajpl | 1 Iondtn | 2026-04-15 | N/A |
| The NASA’s Interplanetary Overlay Network (ION) is an implementation of Delay/Disruption Tolerant Networking (DTN). A segmentation fault occurs with ION-DTN BPv7 software version 4.1.3 when a bundle with a Destination Endpoint ID (EID) set to dtn:none is received. This causes the node to become unresponsive to incoming bundles, leading to a Denial of Service (DoS) condition. This vulnerability is fixed in 4.1.3s. | ||||
| CVE-2025-61910 | 1 Nasajpl | 1 Iondtn | 2026-04-15 | 7.5 High |
| The NASA’s Interplanetary Overlay Network (ION) is an implementation of Delay/Disruption Tolerant Networking (DTN). A BPv7 bundle with a malformed extension block causes uncontrolled memory allocation inside ION-DTN 4.1.3s, leading to receiver thread termination and a Denial-of-Service (DoS). The triggering bundle contains an extension block starting at `0x85070201005bbb0e20b4ea001a000927c0...`. The first byte in the extension block (0x85) indicates a CBOR array of five elements of which the first four are numbers (0x07, 0x02, 0x01, 0x00) but the fifth element is a byte string of length 27 (`0x5bbb0e20b4ea001a000927c0...`). The vulnerability seems to be due to processing the fifth element of the array (i.e., the byte string) as replacing it with a number makes the vulnerability no longer be triggered. While parsing this extension block, ION obtains a very large block length, which in the code in `bei.c`:764) seems to be passed from `blockLength` which is an unsigned int, to a 32 bit signed integer `blkSize`. The unsigned to signed conversion causes `blkSize` to hold the value of -369092043, which is then converted into a 64-bit unsigned value inside `MTAKE(blkSize)`, resulting in an attempt to allocate an unrealistic amount of memory, causing the error. As of time of publication, no known patched versions of BPv7 exist. | ||||
