The flaw can lead to an implicit intent hijacking due to incorrect handling of certain system-level operations. An attacker exploiting this vulnerability can intercept and manipulate these <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-3848-privilege-escalation-vulnerability-in-wp-smartpay-plugin-for-wordpress\/\"  data-wpil-monitor-id=\"92067\">implicit intents to escalate<\/a> their privileges within the system. This can be done without any additional execution privileges and does not require user interaction.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-1904889219\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The following pseudocode provides a conceptual example of how the vulnerability could be exploited:<\/p>\n<pre><code class=\"\" data-line=\"\">Intent maliciousIntent = new Intent();\nmaliciousIntent.setFlags(Intent.FLAG_RECEIVER_FOREGROUND);\nmaliciousIntent.setComponent(new ComponentName(&quot;com.system.app&quot;,&quot;com.system.app.Receiver&quot;));\nBundle maliciousBundle = new Bundle();\nmaliciousBundle.putString(&quot;extra_key&quot;,&quot;malicious_value&quot;);\nmaliciousIntent.putExtras(maliciousBundle);\ncontext.sendBroadcast(maliciousIntent);<\/code><\/pre>\n<p>In this example, the attacker creates a malicious intent, sets it as a foreground receiver, and uses it to target a system app&#8217;s receiver. The malicious intent contains an extra bundle with a malicious value that could be used to cause unexpected behavior in the targeted system app.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>The primary mitigation method for this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, or if a patch is not yet available, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block potential exploit attempts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview CVE-2025-48558 is a high-severity vulnerability that targets the BatteryService.java functions.
