We try to avoid using Nokogiri in modules due to the sometimes
uncomfortable dependencies it creates with particular compiled libxml
versions. Also, the previous parse_xml doesn't seem to be correctly
skipping item entries with blank names.
I will paste the test XML in the PR proper, but do check against a live
target to make sure I'm not screwing it up.
This function takes advantage of MSTIME's CTIMEAnimationBase::put_values
function that's suitable for a no-spray technique (based on wtfuzz's
PoC for MS13-008)
When hashes for params contain nils, they should be converted to empty
strings instead of crashing.
* #to_s: Calls #to_s on vars_get and vars_post data
* #set_encode_uri: Calls #to_s on its arg
When a module is configured to listen on the INADDR_ANY interface, with
a payload that does not have an LHOST option, it attempts to determine
the srvhost from a client socket which would only be available when the
module has included the TcpClient mixin (i.e., it is both passive and
aggressive stance), causing a NameError for the undefined +sock+.
This commit fixes the problem in two ways:
1. It changes the default cli in get_uri to be the module's self.cli,
which should always be set when passive modules would need it (e.g., in
the on_request_uri method).
2. It adds a check to make sure that the calling module has a sock
before trying to get its peerhost. This was @marthieubean's suggested
solution in #1775.
[Closes#1775]
An earlier change to the framework (prepend_migrate) forced single
payloads to use the internal_generate method of payload.rb.
internal_generate calls build which has a cache to track assembled
payloads. This method assumes that a payload only needs to be
assembled once, with optional values patched in later.
Single payloads do not work this way. Each time they are generated
new assembly source is created with the options hardcoded in.
This fix updates build to use the hashcode of the assembly code as
part of the cache key.
This fixes#7898 -- a bug that prevents a user from generating
multiple variations of a single payload without a restart.
