Remove sessions on user password update When a user's password is changed, existing Redfish sessions for that user, created with the old password, continue to work. As per OWASP session management, "The session ID must be renewed or regenerated by the web application after any privilege level change within the associated user session... Common scenarios to consider include; password changes, permission changes, or switching from a regular user role to an administrator role within the web application." [1] https://cheatsheetseries.owasp.org/cheatsheets/Session_Management_Cheat_Sheet.html This commit removes existing user sessions when the user's password is changed. This commit leaves the current session in place though a new removeSessionsByUsernameExceptSession(). This commit doesn't completely get us fully to what owasp says but is a start. Tested: Create some users: ``` curl -k -v -X POST -H "Content-Type: application/json" \ https://$bmc/redfish/v1/AccountService/Accounts/ -d \ '{"UserName":"testadminuser","Password":"<password>","RoleId":"Administrator","Enabled":true}' ``` Using basic auth was able to update own password and another user's password. Using token auth, verified the current session did not get deleted but other sessions from that user did. ``` curl -k -H "Content-Type: application/json" -X POST -D headers.txt \ https://${bmc}/redfish/v1/SessionService/Sessions -d \ '{"UserName":"testadminuser", "Password":"<password>"}' ``` ``` curl -k -v -X PATCH -H "X-Auth-Token: $token" \ -H "Content-Type:application/json" \ https://$bmc/redfish/v1/AccountService/Accounts/testadminuser \ -d '{"Password":"<password>"}' ``` Verified when changing another user's password all sessions were dropped.

This component attempts to be a "do everything" embedded webserver for OpenBMC.
The webserver implements a few distinct interfaces:
bmcweb at a protocol level supports http and https. TLS is supported through OpenSSL.
Bmcweb supports multiple authentication protocols:
Each of these types of authentication is able to be enabled or disabled both via runtime policy changes (through the relevant Redfish APIs) or via configure time options. All authentication mechanisms supporting username/password are routed to libpam, to allow for customization in authentication implementations.
All authorization in bmcweb is determined at routing time, and per route, and conform to the Redfish PrivilegeRegistry.
*Note: Non-Redfish functions are mapped to the closest equivalent Redfish privilege level.
bmcweb is configured per the meson build files. Available options are documented in meson_options.txt
meson setup builddir ninja -C builddir
If any of the dependencies are not found on the host system during configuration, meson will automatically download them via its wrap dependencies mentioned in bmcweb/subprojects
.
bmcweb relies on some on-system data for storage of persistent data that is internal to the process. Details on the exact data stored and when it is read/written can seen from the persistent_data
namespace.
When SSL support is enabled and a usable certificate is not found, bmcweb will generate a self-signed a certificate before launching the server. Please see the bmcweb source code for details on the parameters this certificate is built with.
bmcweb is capable of aggregating resources from satellite BMCs. Refer to AGGREGATION.md for more information on how to enable and use this feature.
