Detailsinfo

A vulnerability classified as problematic has been found in Huawei DP300, RP200, TE50, TE60 and VP9660 (Unified Communication Software). This affects some unknown processing of the component System Manager. The manipulation as part of a Putty Key leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

Huawei DP300 V500R002C00; RP200 V500R002C00; V600R006C00; TE30 V100R001C10; V600R006C00; TE50 V600R006C00; TE60 V100R001C10; V500R002C00; V600R006C00; VP9660 V500R002C10 have an DoS vulnerability due to insufficient validation of the parameter when a putty comment key is loaded. An authenticated remote attacker can place a malformed putty key file in system when a system manager load the key an infinite loop happens which lead to reboot the system.
