Dell Networking OS10 versions 10.4.3.x, 10.5.0.x and 10.5.1.x contain an information exposure vulnerability. A low privileged authenticated malicious user can gain access to SNMP authentication failure messages.

Weakness

The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.

Affected Software

Name Vendor Start Version End Version
Networking_os10 Dell * 10.4.3.8 (excluding)
Networking_os10 Dell 10.5.0.0 (including) 10.5.0.10 (excluding)
Networking_os10 Dell 10.5.1.0 (including) 10.5.1.10 (excluding)
Networking_os10 Dell 10.5.2.0 (including) 10.5.2.8 (excluding)

Potential Mitigations

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable’s type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
