VAR-201309-0394
Vulnerability from variot - Updated: 2025-04-11 23:14Buffer overflow in the PPP Access Concentrator (PPPAC) on the SEIL/x86 with firmware before 2.82, SEIL/X1 with firmware before 4.32, SEIL/X2 with firmware before 4.32, SEIL/B1 with firmware before 4.32, SEIL/Turbo with firmware before 2.16, and SEIL/neu 2FE Plus with firmware before 2.16 allows remote attackers to execute arbitrary code via a crafted L2TP message. SEIL Series routers contain a buffer overflow vulnerability. The PPP Access Concentrator (PPPAC) in SEIL Series routers provided by Internet Initiative Japan Inc. contains a buffer overflow vulnerability in processing L2TP messages.An attacker may execute an arbitrary code on the vulnerable system. The SEIL Router is a router from Japan's SEIL vendors. SEIL series routers, including SEIL/x86, SEIL/B1, SEIL/X1, SEIL/X2, Turbo, and neu 2FE Plus are prone to a buffer-overflow vulnerability because they fails to sufficiently bounds check user-supplied data Attackers can exploit this issue to execute arbitrary code in context of the affected device or cause denial-of-service conditions. SEIL/x86, etc. The following products and versions are affected: SEIL/x86 devices with firmware prior to 2.82, SEIL/X1 devices with firmware prior to 4.32, SEIL/X2 devices with firmware prior to 4.32, SEIL/B1 devices with firmware prior to 4.32 , SEIL/Turbo devices using firmware earlier than 2.16, and SEIL/neu 2FE Plus devices using firmware earlier than 2.16

"data": "Buffer overflow in the PPP Access Concentrator (PPPAC) on the SEIL/x86 with firmware before 2.82, SEIL/X1 with firmware before 4.32, SEIL/X2 with firmware before 4.32, SEIL/B1 with firmware before 4.32, SEIL/Turbo with firmware before 2.16, and SEIL/neu 2FE Plus with firmware before 2.16 allows remote attackers to execute arbitrary code via a crafted L2TP message. SEIL Series routers contain a buffer overflow vulnerability. The PPP Access Concentrator (PPPAC) in SEIL Series routers provided by Internet Initiative Japan Inc. contains a buffer overflow vulnerability in processing L2TP messages.An attacker may execute an arbitrary code on the vulnerable system. The SEIL Router is a router from Japan\u0027s SEIL vendors. SEIL series routers, including SEIL/x86, SEIL/B1, SEIL/X1, SEIL/X2, Turbo, and neu 2FE Plus are prone to a buffer-overflow vulnerability because they fails to sufficiently bounds check user-supplied data\nAttackers can exploit this issue to execute arbitrary code in context of the affected device or cause denial-of-service conditions. SEIL/x86, etc. The following products and versions are affected: SEIL/x86 devices with firmware prior to 2.82, SEIL/X1 devices with firmware prior to 4.32, SEIL/X2 devices with firmware prior to 4.32, SEIL/B1 devices with firmware prior to 4.32 , SEIL/Turbo devices using firmware earlier than 2.16, and SEIL/neu 2FE Plus devices using firmware earlier than 2.16",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
