lib/MT/Upgrade.pm in mt-upgrade.cgi in Movable Type 4.2x and 4.3x through 4.38 does not require authentication for requests to database-migr

lib/MT/Upgrade.pm in mt-upgrade.cgi in Movable Type 4.2x and 4.3x through 4.38 does not require authentication for requests to database-migration functions, which allows remote attackers to conduct eval injection and SQL injection attacks via crafted parameters, as demonstrated by an eval injection attack against the core_drop_meta_for_table function, leading to execution of arbitrary Perl code.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

nvd-primary

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.

The bug in code

The whole CWE-287 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

ts
app.use("/admin", requireSession, adminRouter);
// Route added later skips the middlewareapp.post("/admin-api/config", updateConfig);

Fixed

ts
const admin = express.Router();admin.use(requireSession, requireRole("admin"));
admin.post("/config", updateConfig);app.use("/admin", admin);

Attack context

MITRE CAPEC attack patterns and ATT&CK techniques for this weakness class (CWE). A starting point for detection rules and threat hunting.
