CVE-2017-15349
Description
Huawei CloudEngine 12800 V100R003C00, V100R005C00, V100R005C10, V100R006C00,CloudEngine 5800 V100R003C00, V100R005C00, V100R005C10, V100R006C00,CloudEngine 6800 V100R003C00, V100R005C00, V100R005C10, V100R006C00,CloudEngine 7800 V100R003C00, V100R005C00, V100R005C10, V100R006C00 have a memory leak vulnerability. An unauthenticated attacker may send specific Resource ReServation Protocol (RSVP) packets to the affected products. Due to not release the memory to handle the packets, successful exploit will result in memory leak of the affected products and lead to a DoS condition.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Unauthenticated attackers can cause a denial of service via memory leak by sending crafted RSVP packets to affected Huawei CloudEngine switches.
Vulnerability
A memory leak vulnerability exists in the Resource ReServation Protocol (RSVP) packet handling of Huawei CloudEngine 12800, 5800, 6800, and 7800 series switches. Affected versions include V100R003C00, V100R005C00, V100R005C10, and V100R006C00 for each model. The software fails to release memory allocated to process specific RSVP packets, leading to progressive memory exhaustion [1].
Exploitation
An unauthenticated attacker with network access to the affected device can send specially crafted RSVP packets. No authentication or prior access is required. The attacker simply transmits these packets to the target switch, triggering the memory leak without any user interaction [1].
Impact
Successful exploitation results in a denial of service (DoS) condition due to memory exhaustion. The device may become unresponsive or crash, disrupting network operations. No other impact (e.g., data disclosure or privilege escalation) has been reported [1].
Mitigation
Huawei has released software updates to fix this vulnerability. For example, CloudEngine 12800 users should upgrade to V200R002C50SPC800 or later. The advisory (huawei-sa-20171201-01-router) provides the full list of resolved versions. No workarounds are documented; upgrading is the recommended action [1].
