Deep Dive
A critical vulnerability in Zcash nodes, discovered by security researcher Alex "Scalar" Sol, could have allowed malicious miners to drain approximately 25,000 ZEC (worth about $6.5 million) from the network's deprecated Sprout shielded pool. The flaw, which spanned releases from July 2020 to the present, involved zcashd nodes skipping proof verification for transactions in the legacy Sprout pool. Fortunately, the bug was not exploited, and all user funds remain secure.
Zcash developers released version v6.12.0 on Tuesday to address the vulnerability. Major mining pools acted swiftly to deploy the patch. Luxor confirmed deployment on March 25, followed by F2Pool, ViaBTC, and AntPool by March 26. The Zebra full node implementation was unaffected and would have provided an additional layer of network protection by triggering a chain fork if exploitation had been attempted.
Alex "Scalar" Sol reported the vulnerability to Shielded Labs on March 23, utilizing AI assistance in his discovery. Shielded Labs coordinated with the Zcash Open Development Lab (ZODL), whose engineer Jack "str4d" Grigg authored the fix. Sol is set to receive a total bounty of 200 ZEC, valued at over $51,000, with contributions from Shielded Labs, ZODL, the Zcash Foundation, and Bootstrap.
The Sprout pool, closed to new deposits in November 2020, still holds around 25,424 ZEC that have not been migrated to newer shielded pools. While the vulnerability could have facilitated the draining of these funds, Zcash's "turnstile" mechanism would have prevented broader supply inflation. This mechanism ensures that coins leaving the Sprout pool must have verifiably entered it, acting as a safeguard against the creation of new tokens beyond the network's total circulation of approximately 16.63 million ZEC.
This incident follows a previous vulnerability discovered in 2019, an "infinite counterfeit" crypto generator, which was patched before causing significant issues. In recent market activity, Zcash has been a notable gainer among the top 100 cryptocurrencies, rising over 14% to a price above $255 in the last 24 hours. This follows a significant price surge last fall and subsequent declines mirroring broader market trends.
