Bug ID: 63912
Summary: Inconsistent authorization process for dbm cannot open
error
Product: Apache httpd-2
Version: 2.5-HEAD
Hardware: PC
OS: All
Status: NEW
Severity: major
Priority: P2
Component: mod_authn_dbm
Assignee: bugs@httpd.apache.org
Reporter: lege...@foxmail.com
Target Milestone: ---
In function
static authz_status dbmgroup_check_authorization(request_rec *r,
const char *require_args,
const void
*parsed_require_args)
...
status = get_dbm_grp(r, apr_pstrcat(r->pool, user, ":", realm, NULL),
user, conf->grpfile, conf->dbmtype, &groups);
if (status != APR_SUCCESS) {
ap_log_rerror(APLOG_MARK, APLOG_ERR, status, r, APLOGNO(01799)
"could not open dbm (type %s) group access "
"file: %s", conf->dbmtype, conf->grpfile);
return AUTHZ_GENERAL_ERROR;
}
}
If the dbm file cannot be opened, such authorization will be returned with
AUTHZ_GENERAL_ERROR. However, there is an inconsistent behavior of such cases
just in another method:
static authz_status dbmfilegroup_check_authorization(request_rec *r,
const char *require_args,
const void
*parsed_require_args)
{
...
status = get_dbm_grp(r, apr_pstrcat(r->pool, user, ":", realm, NULL),
user, conf->grpfile, conf->dbmtype, &groups);
if (status != APR_SUCCESS) {
ap_log_rerror(APLOG_MARK, APLOG_ERR, status, r, APLOGNO(01803)
"could not open dbm (type %s) group access "
"file: %s", conf->dbmtype, conf->grpfile);
return AUTHZ_DENIED;
}
...
}
Such authorization will be denied by AUTHZ_DENIED.
