Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
Parse dsn connection url strings. Responsible for parsing dsn strings in projects like prom and morp.
This is a generic version of dj-database-url.
So, now you can create dsns like this:
scheme://user:pass@host:port/path?query=query_val#fragment
For example, let's look at a prom dsn:
prom.interface.postgres.Interface://testuser:testpw@localhost/testdb
Now let's parse it:
import dsnparse
dsn = "prom.interface.postgres.Interface://testuser:testpw@localhost:1234/testdb"
r = dsnparse.parse(dsn)
print(r.scheme) # prom.interface.postgres.Interface
print(r.username) # testuser
print(r.password) # testpw
print(r.host) # localhost
print(r.port) # 1234
print(r.hostloc) # localhost:1234
print(r.paths) # ['testdb']
Also, dsnparse can easily use environment variables:
r = dsnparse.parse_environ('ENVIRONMENT_VARIABLE_NAME')
I tried to keep the interface very similar to urlparse so it will feel familiar to use.
By default, dsnparse.parse(dsn)
returns a ParseResult
instance, but that can be customized:
import dsnparse
class MyResult(dsnparse.ParseResult):
def configure(self):
# expose an interface property
self.interface = self.scheme
dsn = "Interface://testuser:testpw@localhost:1234/testdb"
r = dsnparse.parse(dsn, parse_class=MyResult)
print(isinstance(r, MyResult)) # True
print(r.interface) # Interface
Use pip:
pip install dsnparse
or use pip with github:
pip install -U "git+https://github.com/Jaymon/dsnparse#egg=dsnparse"
