Cybersecurity researchers have discovered a number of suspicious packages published to the npm registry that are designed to harvest Ethereum private keys and gain remote access to the machine via the secure shell (SSH) protocol. The packages attempt to "gain SSH access to the victim's machine by writing the attacker’s SSH public key in the root user’s authorized_keys file," software supply

### Summary In `elliptic`-based version, `loadUncompressedPublicKey` has a check that the public key is on the curve: https://github.com/cryptocoinjs/secp256k1-node/blob/6d3474b81d073cc9c8cc8cfadb580c84f8df5248/lib/elliptic.js#L37-L39 `loadCompressedPublicKey` is, however, missing that check: https://github.com/cryptocoinjs/secp256k1-node/blob/6d3474b81d073cc9c8cc8cfadb580c84f8df5248/lib/elliptic.js#L17-L19 That allows the attacker to use public keys on low-cardinality curves to extract enough information to fully restore the private key from as little as 11 ECDH sessions, and very cheaply on compute power Other operations on public keys are also affected, including e.g. `publicKeyVerify()` incorrectly returning `true` on those invalid keys, and e.g. `publicKeyTweakMul()` also returning predictable outcomes allowing to restore the tweak ### Details The curve equation is `Y^2 = X^3 + 7`, and it restores `Y` from `X` in `loadCompressedPublicKey`, using `Y = sqrt(X^3 + 7)`, but whe...

Versions of the package http-proxy-middleware before 2.0.7, from 3.0.0 and before 3.0.3 are vulnerable to Denial of Service (DoS) due to an UnhandledPromiseRejection error thrown by micromatch. An attacker could kill the Node.js process and crash the server by making requests to certain paths.

### Impact matrix-react-sdk before 3.102.0 allows a malicious homeserver to potentially steal message keys for a room when a user invites another user to that room, via injection of a malicious device controlled by the homeserver. This is possible because matrix-react-sdk before 3.102.0 shared historical message keys on invite. ### Patches matrix-react-sdk 3.102.0 [disables sharing message keys on invite](https://github.com/matrix-org/matrix-react-sdk/pull/12618) by removing calls to the vulnerable functionality. ### Workarounds None. ### References The vulnerability in matrix-react-sdk is caused by calling `MatrixClient.sendSharedHistoryKeys` in matrix-js-sdk, which is inherently vulnerable to this sort of attack. This matrix-js-sdk vulnerability is tracked as CVE-2024-47080 / [GHSA-4jf8-g8wp-cx7c](https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-4jf8-g8wp-cx7c). Given that this functionality is not specific to sharing message keys on *invite*, is optional, ...

# Description ## Path traversal This vulnerability allows an attacker to craft a request which is able to traverse the server file system and retrieve the contents of arbitrary files, including sensitive data such as configuration files, environment variables, and other critical data stored on the server. From Rajesh Sharma who discovered the vulnerability: POC: `curl --path-as-is http://localhost:3000/assets/../package.json` gives you the content of package.json present in the local directory. The vulnerability stems from usage of decodedReqPath directly in path.join without performing any path normalization i.e path.normalize in node.js https://github.com/vendure-ecommerce/vendure/blob/801980e8f599c28c5059657a9d85dd03e3827992/packages/asset-server-plugin/src/plugin.ts#L352-L358 If the vendure service is behind some server like nginx, apache, etc. Path normalization is performed on the root server level but still the actual client's request path will be sent to vendure service ...

The Elliptic package 6.5.7 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. This leads to valid signatures being rejected. Legitimate transactions or communications may be incorrectly flagged as invalid.

Cybersecurity researchers have found that entry points could be abused across multiple programming ecosystems like PyPI, npm, Ruby Gems, NuGet, Dart Pub, and Rust Crates to stage software supply chain attacks. "Attackers can leverage these entry points to execute malicious code when specific commands are run, posing a widespread risk in the open-source landscape," Checkmarx researchers Yehuda
