CVE-2017-15871

Exp

The deserialize function in serialize-to-js through 1.1.1 allows attackers to cause a denial of service via vectors involving an Immediately Invoked Function Expression "function()" substring, as demonstrated by a "function(){console.log(" call or a simple infinite loop. NOTE: the vendor agrees that denial of service can occur but notes that deserialize is explicitly listed as "harmful" within the README.md file

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
