A new malware campaign has been exploiting the updating mechanism of the eScan antivirus software to distribute backdoors and cryptocurrency miners like XMRig through a long-standing threat codenamed GuptiMiner targeting large corporate networks. Cybersecurity firm Avast said the activity is the work of a threat actor with possible connections to a North Korean hacking group dubbed

A new ongoing malware campaign has been observed distributing three different stealers, such as CryptBot, LummaC2, and Rhadamanthys hosted on Content Delivery Network (CDN) cache domains since at least February 2024. Cisco Talos has attributed the activity with moderate confidence to a threat actor tracked as CoralRaider, a suspected Vietnamese-origin

SQL injection vulnerability in Zend Framework before 1.12.9, 2.2.x before 2.2.8, and 2.3.x before 2.3.3, when using the sqlsrv PHP extension, allows remote attackers to execute arbitrary SQL commands via a null byte.

A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple attack vectors on a Drupal site, which could result in the site being compromised. This vulnerability is related to Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-002. Both SA-CORE-2018-002 and this vulnerability are being exploited in the wild.

### Impact Title argument in Markdown for links and images not escaped in internal render hooks. Impacted are Hugo users who have these hooks enabled and do not trust their Markdown content files. ### Patches Patched in v0.125.3. ### Workarounds Replace with user defined templates or disable the internal templates: https://gohugo.io/getting-started/configuration-markup/#renderhooksimageenabledefault ### References https://github.com/gohugoio/hugo/releases/tag/v0.125.3

### Summary Conform allows the parsing of nested objects in the form of `object.property`. Due to an improper implementation of this feature, an attacker can exploit it to trigger prototype pollution by passing a crafted input to `parseWith...` functions. ### PoC ```javascript const { parseWithZod } = require('@conform-to/zod'); const { z } = require("zod"); const param = new URLSearchParams("__proto__.pollution=polluted"); const schema = z.object({ "a": z.string() }); parseWithZod(param, { schema }); console.log("pollution:", ({}).pollution); // should print "polluted" ``` ### Details The invocation of the `parseWithZod` function in the above PoC triggers the `setValue` function through `getSubmissionContext` and `parse`, executing the following process, resulting in prototype pollution: ```javascript let pointer = value; pointer.__proto__ = pointer.__proto__; pointer = pointer.__proto__; pointer.polluted = "polluted"; ``` This is caused by the lack of object existence checki...

### Impact A remote Matrix user with malicious intent, sharing a room with Synapse instances before 1.105.1, can dispatch specially crafted events to exploit a weakness in how the auth chain cover index is calculated. This can induce high CPU consumption and accumulate excessive data in the database of such instances, resulting in a denial of service. Servers in private federations, or those that do not federate, are not affected. ### Patches Server administrators should upgrade to 1.105.1 or later. ### Workarounds One can: - ban the malicious users or ACL block servers from the rooms; and/or - leave the room and purge the room using the admin API ### For more information If you have any questions or comments about this advisory, please email us at [security AT element.io](mailto:[email protected]).

### SpEL Injection in `PUT /api/v1/policies` (`GHSL-2023-252`) **Please note, only authorized and admin role users have access to PUT / POST APIS for /api/v1/policies. Non authenticated users will not be able to access these APIs to exploit the vulnerability** `CompiledRule::validateExpression` is also called from [`PolicyRepository.prepare`](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-service/src/main/java/org/openmetadata/service/jdbi3/PolicyRepository.java#L113) ```java @Override public void prepare(Policy policy, boolean update) { validateRules(policy); } ... public void validateRules(Policy policy) { List<Rule> rules = policy.getRules(); if (nullOrEmpty(rules)) { throw new IllegalArgumentException(CatalogExceptionMessage.EMPTY_RULES_IN_POLICY); } // Validate all the expressions in the rule for (Rule rule : rules) { CompiledRule.validateExpression(rule.getCondition(), Boolean.class); rule.getResources...
