Some Huawei S series switches have a DoS vulnerability. An unauthenticated remote attacker can send crafted packets to the affected device to exploit this vulnerability. Due to insufficient verification of the packets, successful exploitation may cause the device reboot and denial of service (DoS) condition. (Vulnerability ID: HWPSIRT-2019-03109)
Huawei AC6605 with software V200R001C00; AC6605 with software V200R002C00; ACU with software V200R001C00; ACU with software V200R002C00; S2300, S3300, S2700, S3700 with software V100R006C05 and earlier versions; S5300, S5700, S6300, S6700 with software V100R006, V200R001, V200R002, V200R003, V200R005C00SPC300 and earlier versions; S7700, S9300, S9300E, S9700 with software V100R006, V200R001, V200R002, V200R003, V200R005C00SPC300 and earlier versions could allow remote attackers to send a special SSH packet to the VRP device to cause a denial of service.
Memory leak in Huawei S9300, S5300, S5700, S6700, S7700, S9700, and S12700 devices allows remote attackers to cause a denial of service (memory consumption and restart) via a large number of malformed packets.
Huawei S7700, S9300, S9700, and S12700 devices with software before V200R008C00SPC500 use random numbers with insufficient entropy to generate self-signed certificates, which makes it easier for remote attackers to discover private keys by leveraging knowledge of a certificate.
Memory leak in Huawei S5300EI, S5300SI, S5310HI, and S6300EI Campus series switches with software V200R003C00 before V200R003SPH011 and V200R005C00 before V200R005SPH008; S2350EI and S5300LI Campus series switches with software V200R003C00 before V200R003SPH011, V200R005C00 before V200R005SPH008, and V200R006C00 before V200R006SPH002; S9300, S7700, and S9700 Campus series switches with software V200R003C00 before V200R003SPH011, V200R005C00 before V200R005SPH009, and V200R006C00 before V200R006SPH003; S5720HI and S5720EI Campus series switches with software V200R006C00 before V200R006SPH002; and S2300 and S3300 Campus series switches with software V100R006C05 before V100R006SPH022 allows remote authenticated users to cause a denial of service (memory consumption and device restart) by logging in and out of the (1) HTTPS or (2) SFTP server, related to SSL session information.
Memory leak in Huawei S5300EI, S5300SI, S5310HI, S6300EI/ S2350EI, and S5300LI Campus series switches with software V200R001C00 before V200R001SPH018, V200R002C00 before V200R003SPH011, and V200R003C00 before V200R003SPH011; S9300, S7700, and S9700 Campus series switches with software V200R001C00 before V200R001SPH023, V200R002C00 before V200R003SPH011, and V200R003C00 before V200R003SPH011; and S2300 and S3300 Campus series switches with software V100R006C05 before V100R006SPH022 allows remote attackers to cause a denial of service (memory consumption and reboot) via a large number of ICMPv6 packets.
